The Works of Antoni Gaudí in Barcelona
Casa Batlló.
Everyone knows about La Sagrada Familia as it is one of Spain’s number one attractions. But several other Gaudí works in Barcelona are also classified as UNESCO world heritage sites in Spain. These include Parc Güell, Palacio Güell, Casa Milà, Casa Vicens, Casa Batlló, and the Crypt in Colonia Güell.
Gaudí is not the only modernist architect with works in Barcelona with a UNESCO designation.
Architect Lluís Domènech i Montaner’s Palau de la Música Catalana and Hospital de Sant Pau are also both (rightfully) UNESCO sites as well.
Architecture lovers might want to consider a private Barcelona walking tour. to get an up-close perspective as well as visit some of the Modernista gems of Barcelona off the beaten path.
2. Córdoba’s Historic Center
The entire historic center of Córdoba, located in Andalucía Spain, is a designated UNESCO site. Therefore, Córdoba boasts one of the largest world heritage sites in all of Europe.
The quaint streets of Córdoba’s historic center.
Included is the famous Mezquita Mayor, which used to be a mosque, but was turned into a cathedral in the 1200s. Known for its mesmerizing arches, evidence of both faiths can be found in this unique building. Make sure to also spend some time wandering Córdoba’s small streets. You will soon understand why the whole centro histórico is included on the UNESCO list.
(This is one of the top cathedrals in Spain!)
Córdoba’s annual Fiesta de los Patios is my personal favorite festival in all of Spain. Want to go next year? Let’s get in touch (We are host an exclusive la Fiesta de los Patios for the Travel Spain! Community every May.
Be sure that you are a member of our community or join our email list to hear more details and to join us!)
Have a listen to the When in Spain podcast where Spain Less Traveled founder, Karen, was a guest talking about la Fiesta de los Patios!
(And finally, here are some other handpicked top things to do in Cordoba Spain!)
3. The Medina Azahara just outside of Córdoba
When we think of ruins, we usually think of Roman ruins. But just outside of Córdoba’s city limits, you can view impressive Moorish ruins.
The impressive Moorish ruins at the Medina Azahara.
Córdoba was the capital of the Muslim world in the early middle ages. And the Medina Azahara (or Medinat al-Zahara) is what was the capital of the Caliphate of Córdoba.
For hundreds of years, this ancient city was forgotten. But in the early 1990s, the ruins were excavated. Today they are some of the best-preserved Moorish ruins in the world.
It is now a UNESCO World Heritage Site.
There is an informative museum explaining the history of the Medina Azahara. But the real treat is getting to wander around what remains of the palace complex and the mosque. The site is impressive and was surely fit for royalty!
Amongst these ruins, you will find old infrastructure such as roads, bridges, aqueduct systems, and buildings. While you can explore the site on your own, we recommend going with a tour guide who can explain it and make it come to life.
4. The Renaissance Architecture in Úbeda and Baeza
Capilla del Salvador in Úbeda Spain.
Both Úbeda and Baeza, in Andalucía’s Jaén province are on the list of UNESCO World Heritage sites in Spain for their Renaissance Architecture.
Back in the 1600s, both towns were renovated and rebuilt using the emerging style of Renaissance architecture, making them some of Spain’s first places to construct in this up and coming style at the time.
Úbeda’s Palacio de las Cadenas and Capilla del Salvador in Plaza de Vazquez de Molina are prime examples of this.
Nearby Baeza is noted for having some of the best Italian Renaissance architecture in all of Spain.
Úbeda and Baeza are some of Andalucía’s less traveled gems.

5. The Roman Ruins at Mérida
Mérida, is not only the capital of Extremadura. At one point it was the capital of Lusitania, a province in ancient Rome. The Roman ruins of Mérida are the most impressive in all of Spain, earning it a designation as one of the UNESCO World Heritage sites in Spain.
Simply wander around Mérida, and you’re bound to find ruins in the most random places.
But there are some highly impressive sites too. Some of the highlights include the Roman bridge, circus, Arco (arch of) de Trajano, and Templo (temple of) de Diana.
Roman Theater in Mérida, Spain which hosts summer concerts!
If you are lucky you can even catch a performance at the Roman Theater. Imagine watching a play surrounded by that much history!
Mérida, Spain must be on your bucket list if you are the type of traveler who loves visiting Roman ruins. Unlike in Italy or even other parts of Spain, there are few crowds in Mérida, letting you get up close and personal with some of the Roman Empire’s best preserved ruins.
(Here are even more reasons to visit Extremadura Spain!)
6. The Dólmenes in Antequera
Antequera in Málaga province is home to a one of a kind series of megalithic monuments. It is one of our favorite day trips from Málaga city.
Entrance to Viera Dolmen.
These ancient burial sites were architectural wonders from their time (the Neolithic and Bronze Ages, to be exact). Built between 3500BC and 2500BC, travelers can visit all three sites: Menga Dolmen and the Viera Dolmen are walkable from Antequera’s historic center while the newer Tholos of El Romeral is a few kilometers out of town.
The Menga Dolmen, in particular, is noted for its geographical location - during Summer Solstice the morning sun shines over the peak of the hill over the dolmen, straight along the to its entrance. This very exact positioning would have held mystical importance for the tribes who constructed the dolmen many years ago. The Menga Dolmen is also noted for its pillars, which were said to be the only ones in the world.
The dolmens are free to enter, but you need to register at the visitors’ center first After making a loop around the hills they were constructed on, visitors are free to walk into the caves. It is impressive how much of the original structure still remains.
Just a short distance from Málaga city, there are so many reasons to visit Antequera!
7. The Mudéjar Buildings in Aragón
The Mudéjar style buildings in Teruel are included on list of UNESCO World Heritage Sites in Spain.
Mudéjar is an architectural style unique to Spain. Although you can find buildings in this style in several areas of Spain, the Aragón area has so many gems that UNESCO listed “the Mudéjar Architecture of Aragon” to their list. This style was developed by the Catholics but was meant to mimic the Moorish style. The reason behind it? Economics. It was less expensive to design buildings in Mudéjar style.
Some of the best places in Aragón to see these architectural gems are Zaragoza, the largest city in the province, and Teruel, a small, regional city
Furthermore, Zaragoza is convenient. Halfway between Madrid and Barcelona, it is a great stop along the popular route with travelers.
(hint: for more information about less-visited cities like Zaragoza and Teruel be sure to check out our list of top 30 cities in Spain for travelers!)
8. Old Salamanca
The impressive architecture of Salamanca is on the list of UNESCO World Heritage sites in Spain.
Salamanca, in Castilla Y León, is another city where the center earned a UNESCO World Heritage Site mention. All within the small historic center, you can find Renaissance, Baroque, Romanesque, Gothic, and even Moorish buildings. At night these monuments are all lit up gold and are just as impressive as they are during the day.
Do not miss Salamanca’s stunning Plaza Mayor. Bonus points: if you find the frog carved into the facade on of one of the buildings at the University of Salamanca, legend says you’ll have good academic and love luck. It’s there!
Salamanca is a perfect stop on a Spain and Portugal road trip. It is also very easily reached from Madrid via the AVE train.
9. Alcalá de Henares
Looking for an easy day trip from Madrid via commuter train? Look no further than Alcalá de Henares!
The university in Alcalá de Henares is not only one of Spain’s best but is a UNESCO World Heritage Site.
The medieval quarter of Alcalá de Henares, near the university which is a UNESCO World Heritage Site in Spain.
Make sure to also explore the medieval streets near the University. You will quickly learn that Spanish writer, Miguel de Cervantes, was born here. You can visit his birth house as well as find a lot of other tributes to the writer and his most famous work, Don Quixote in Alcalá de Henares.
The city also has a small old Jewish quarter.
(For travelers who want to see much more of Jewish Spain, check out our travel guide to Sephardic Spain.)
10. Valencia’s La Lonja de la Seda
In Spain’s third-largest city, Valencia, right in the center, you will find a Gothic-style marvel that was originally constructed to exchange silk.
The exterior of La Lonja de la Seda in Valencia.
Constructed between 1482 and 1533, this is where silk merchants used to barter and work out trading contracts. The intricately designed complex was the seat of the Tribunal del Mar - the first marine merchant tribunal to ever be formed in Spain.
Now a UNESCO World Heritage site, its listing says that “the site is of outstanding universal value as it is a wholly exceptional example of a secular building in late Gothic style, which dramatically illustrates the power and wealth of one of the great Mediterranean mercantile cities.”
Be sure to pay La Lonja a visit during your time in fabulous Valencia!
11. San Lorenzo de El Escorial
Alcalá de Henares is not the only Madrid day trip option with a UNESCO site.
The monastery at San Lorenzo de El Escorial.
If you want to visit a monastery fit for a king, then make sure to head out to El Escorial, or more specifically San Lorenzo de El Escorial.
One of the most important architectural monuments from the Renaissance, deeply religious King Felipe II wanted a complex for the multiple purposes of a burial place for his father, a religious monastery; and, of course a palace royal enough for a king.
Take some time to tour the complex, the library is noteworthy as some believe that the designers of the Vatican library took their inspiration from El Escorial.
Be sure not to miss this impressive UNESCO World Heritage sites in Spain.
12. Doñana National Park
Be on the lookout for the Iberian lynx at Doñana National Park!
Where the Guadalquivir River meets the Atlantic Ocean, you will find one of Spain’s natural UNESCO World Heritage Sites, Doñana National Park.
If trying your luck at spotting an Iberian lynx* is in the cards, you will want to head to Doñana. This vast area in three provinces (Huelva, Cádiz, and Seville) also boasts a wide variety of birds, including flamingos.
The delta creates sand dunes and a natural barrier which leads to so much biodiversity. This beautiful UNESCO World Heritage site is also one of our favorite natural landscapes in Spain.
Private cars are not allowed in most of the park, but you can book a safari-like tour and test your luck at spotting wildlife.
(*Full disclosure: spotting a lynx is difficult)
13. The Old City Walls in Ávila
And yet another possible day trip from Madrid to visit a UNESCO site. So many options, really!
Ávila’s city walls.
Ávila’s well-preserved old city wall is a UNESCO World Heritage Site in Spain. It was constructed between the 11th and 14th centuries to defend the city against the Moors. There are eight gates and 88 watchtowers.
Visitors can walk most of the walls (2.5 kilometers!), taking in great views of the old city.
Make sure to also spend time exploring the medieval city contained within these historical and intriguing city walls.
14. Oviedo’s Romanesque Churches
Asturias was Spain’s only remaining Christian kingdom in the 9th century, and thus developed its own style of Romanesque art and architecture.
Santa María del Naranco in Oviedo, Spain.
Some of the very best examples of this can be seen in Oviedo, the regional capital of Asturias.
On Mount Naranco, in the lush green hills above the city visitors can Santa María del Naranco and San Miguel de Lillo, the two Romanesque churches that are classified as UNESCO world heritage sites.
Asturias is filled with interesting and historical sites. For more information about Spain’s off the beaten path north, here are some ideas for travelers in Asturias Spain.
15. The Roman Walls of Lugo
Ávila’s city walls aren’t the only fortifications in Spain to be designated as a UNESCO World Heritage site.
Walking the walls in Lugo.
In Galicia Spain, Lugo’s walls are also a one of Spain’s UNESCO World Heritage sites. Not nearly as popular with travelers as the Cathedral (and old town) of Santiago de Compostela, also a UNESCO site in Galicia, Lugo is a real treat for those seeing more off the beaten path destinations.
The walls were built in the 3rd century and still remain very much in tact. UNESCO designated them a world heritage site as they are “the finest example of late Roman fortifications in western Europe.”
Visitors can walk the entire length these walls, nearly 2 kilometers, that loop around Lugo’s historic center. 49 of the original towers are still in tact, with another 39 that are partially in tact. There are 10 gates, 5 of these dating back to the Roman times (the other five were added as the city grew).
(There is so much more to do in Galicia and even more UNESCO World heritage sites there. Check out our guide to Galicia Spain for tips and ideas to explore the region.)
16. Vizcaya Bridge
Vizcaya Bridge
Just outside of Bilbao in Basque Country, designed by Basque architect Alberto de Palacio, is the Vizcaya Bridge (or Bizkaia), another UNESCO World Heritage site.
Completed in 1893, the Vizcaya Bridge links the towns of Portugalete and Getxo. The bridge is considered to be one of the most outstanding representations of the industrial era. It was the first suspended gondola style bridge in the world to carry both traffic as well as pedestrians and was used as a model for this type of bridge construction worldwide.
Visitors can go to the top of the bridge by elevator to check out the views. Or even better, you can ride across the hanging bridge for as little as 50 cents each way!
17. Serra de Tramuntana
The island of Mallorca, part of the Balearic Islands, boasts a unique UNESCO World Heritage site that showcase the its rich history.
Stunning Serra de Tramuntana
The Serra de Tramuntana mountain range, that runs along the northwestern side of the island is renowned for its stunning natural beauty. But not only that, you can see evidence of the traditional agricultural practices carried down from the Muslim times.
According to UNESCO, “an environment with scarce resources has transformed the terrain and displays an articulated network of devices for the management of water revolving around farming units of feudal origins.” Basically, they were able to make the land farmable and habitable for humans.
These days, visitors can explore quaint villages nestled among terraced landscapes and hike along ancient paths in this natural UNESCO World Heritage site in Spain!
The Serra de Tramuntana’s scenery is stunning and holds so much information about Mallorca’s rich history.
18. The Alhambra
It’s no surprise to see the Alhambra in Granada Spain included a list of our favorite UNESCO world heritage sites in Spain.
As famous as it is, the Alhambra is not overrated.
This cornerstone of Moorish architecture always appears on every list of best Islamic architecture in the world along with monuments such as the Taj Mahal and Abu Dhabi’s Sheikh Zayed Mosque. With its palaces, gardens, fortresses, and castle, the Alhambra is a must-see!
