Spain is a country where history doesn’t just live in textbooks—it breathes through the stones of ancient castles, whispers in the corridors of Moorish palaces, and dances in the flickering shadows of Gothic cathedrals. As a travel writer who has spent over a decade wandering its sun-drenched streets and crumbling ruins, I can tell you this: Spain in 2026 is not just a destination; it’s a time machine.
This year, I’ve handpicked five historical gems that you absolutely cannot miss. These aren’t just the usual tourist stops (though some are famous for good reason). These are places that will make your heart race, your imagination soar, and your Instagram feed the envy of all your friends. So, grab your walking shoes, a good camera, and maybe a churro or two—let’s dive in.
Address: Calle Real de la Alhambra, s/n, 18009 Granada, Spain
Hours: 8:30 AM – 6:00 PM (varies by season; night visits available)

If you visit only one historical site in Spain in 2026, make it the Alhambra. This isn’t just a palace—it’s a love letter written in stone, water, and light by the Nasrid dynasty, the last Muslim rulers of Spain. Perched on a hill overlooking Granada, the Alhambra is a masterpiece of Islamic architecture, where every tile, every arch, every trickling fountain tells a story of a bygone era.
The Alhambra has undergone extensive restoration in recent years, and 2026 is the perfect time to see it in all its glory. The Patio de los Leones (Court of the Lions), with its iconic fountain and delicate arches, has been meticulously restored to its original splendor. Walking through the Palacio de Comares, you’ll feel like you’ve stepped into a fairy tale—one where sultans once held court under star-shaped ceilings that seem to float above you.
I’ll never forget my first visit to the Alhambra at sunrise. The air was crisp, the crowds were thin, and as the first golden light hit the red walls of the fortress, I understood why the Moors called it al-Qal'a al-Hamra—the Red Castle. I sat on a bench in the Generalife gardens, surrounded by the scent of orange blossoms, and for a moment, I could almost hear the faint strum of a lute from centuries past.
Address: Plaza Margarita Xirgu, s/n, 06800 Mérida, Spain

If you think Rome’s Colosseum is impressive, wait until you see Mérida’s Roman Theatre. This staggeringly well-preserved ruin in Extremadura is one of the best examples of Roman engineering in the world. Built in 15 BC, it once seated 6,000 spectators who came to watch plays, gladiator battles, and even animal hunts.
Mérida is often overshadowed by more famous Spanish cities, but 2026 is its moment to shine. The city is celebrating the 2,000th anniversary of the theatre’s construction with special performances, including reenactments of ancient Roman plays. Imagine sitting in the same stone seats where Roman citizens once cheered, watching actors in togas bring classical stories to life.
The first thing you’ll notice is the sheer scale of the theatre. The stage, with its towering columns and intricate carvings, is a testament to Roman grandeur. But what really gets me is the acoustics. Stand in the center of the stage and clap your hands—the sound carries perfectly to the top rows, just as it did two millennia ago. Close your eyes, and you can almost hear the roar of the crowd.
Mérida isn’t just about the theatre. The city is a treasure trove of Roman ruins:
Address: Carretera de A-1503, km 2, 50314 Nuévalos, Zaragoza, Spain
Hours: 10:00 AM – 6:00 PM (varies by season)

Tucked away in the hills of Aragon, the Monastery of Piedra is one of Spain’s best-kept secrets. Founded in 1194 by Cistercian monks, this monastery is famous for its stunning natural park, where waterfalls cascade through lush greenery, and hidden caves whisper legends of knights and hermits.
The monastery has recently opened new areas to the public, including restored sections of the monastic buildings and previously off-limits parts of the park. In 2026, they’re also introducing nighttime visits with lantern-lit paths—a magical way to experience the site.
The moment you step into the park, you’ll feel like you’ve entered another world. The sound of water is everywhere—dripping, rushing, roaring. The highlight is the Cola de Caballo (Horse’s Tail), a 50-meter waterfall that plunges into a crystal-clear pool. But my favorite spot is the Grutas de Iris—a series of caves where sunlight filters through the rock, creating an ethereal glow.
Don’t skip the monastic buildings. The cloister, with its simple yet elegant Romanesque arches, is a place of quiet reflection. The church, though partially in ruins, still holds a haunting beauty. I once sat in the chapter house, imagining the monks gathered there centuries ago, their voices echoing off the stone walls.
Address: Av. del Professor López Piñero, 7, 46013 Valencia, Spain
Hours: 10:00 AM – 7:00 PM (varies by attraction)

Wait, a futuristic complex in an article about historical gems? Trust me, the City of Arts and Sciences (Ciudad de las Artes y las Ciencias) is a historical site in the making. Designed by Santiago Calatrava and Félix Candela, this architectural marvel is one of the most important cultural landmarks of the 21st century. But it’s also deeply rooted in Valencia’s history as a center of innovation and art.
The complex is celebrating its 25th anniversary in 2026 with a series of special exhibitions and events. The L’Hemisfèric (a planetarium and IMAX cinema) will be showcasing a new film about Spain’s historical connection to the stars, from Moorish astronomers to modern space exploration.
The moment you see the City of Arts and Sciences, you’ll feel like you’ve stepped into a sci-fi movie. The L’Umbracle, a floating garden, offers panoramic views of the entire complex. The Palau de les Arts Reina Sofía, an opera house that looks like a spaceship, hosts world-class performances. But the real star is the L’Oceanogràfic, Europe’s largest aquarium, where you can walk through underwater tunnels surrounded by sharks and rays.
Valencia has always been a city of innovation. In the Middle Ages, it was a hub of trade and science. The City of Arts and Sciences is a modern homage to that legacy. Walking through its gleaming halls, you’re not just seeing the future—you’re seeing the continuation of a story that began centuries ago.

Hours: Open 24/7 (best visited during daylight)

If you’ve ever dreamed of walking through a medieval village straight out of a storybook, Besalú is your dream come true. This tiny town in Catalonia is one of the best-preserved medieval villages in Spain, with a history that dates back over a thousand years.
Besalú has been quietly gaining attention as a must-visit historical site, but it’s still off the beaten path for most tourists. In 2026, the town is hosting a series of medieval festivals, including jousting tournaments, craft fairs, and even a recreations of a medieval market. It’s like stepping into a time machine.
The iconic Pont de Besalú, a 12th-century bridge with a distinctive angled design, is the town’s most famous landmark. Walking across it, you’ll feel like a knight returning from battle. The bridge was once a crucial crossing point on the Via Augusta, the Roman road that connected Italy to Spain.
Besalú was home to one of the most important Jewish communities in medieval Catalonia. The Mikveh, a Jewish ritual bath from the 12th century, is one of the best-preserved in Europe. Standing in its dimly lit chambers, you can almost hear the whispers of the women who once gathered here.
This Romanesque church, with its intricate carvings and towering bell tower, is a masterpiece of medieval architecture. Climb to the top for a breathtaking view of the village and the surrounding countryside.
Spain is a country where history is alive. Whether you’re standing in the shadow of the Alhambra, listening to the echoes of gladiators in Mérida, or losing yourself in the medieval streets of Besalú, you’re not just seeing the past—you’re feeling it.
In 2026, these five sites offer something extra special. From anniversary celebrations to newly restored wonders, this is the year to experience Spain’s history in all its glory. So pack your bags, book your tickets, and get ready for a journey through time.
And when you’re there, sitting on a sun-warmed stone or sipping a glass of local wine, take a moment to soak it all in. Because these aren’t just places—these are stories waiting to be told.
