La Sagrada Familia (Basilica of the Holy Family), Barcelona (must see)

Up close, Gaudí's grand Gothic masterpiece is truly awe-inspiring. The colossal basilica appears to emerge from the ground, reaching ever higher as far as the eye can see. Gaudí dedicated an impressive 43 years of his career to designing this iconic monument, and the still ongoing construction works are as much part of the attraction as the building itself.

While the exterior offers a lot to admire, the interior is equally extraordinary, with the eyes being drawn at once to the walls and the roof. Immense, luminous stained-glass windows line the walls, flooding the church with natural light and a kaleidoscope of colors. Supported by countless pillars with robust bases that branch out like trees towards the ceiling, the temple's roof resembles a vibrant forest canopy.

Simply wandering around and taking in the sights may suffice in an ordinary church, but the Sagrada Família leaves you clueless as a rock if you decide to do the same here. This cathedral is on a whole other level, and it's worth delving into its fascinating details with the help of a guide. Fortunately, audio devices are available at the entrance, providing ample information while allowing enough time for exploration. Alternatively, you can book a guided tour in your preferred language directly on the basilica's website.

When planning your visit, pre-purchasing a ticket online is absolutely recommended and will let you skip the long queues upon arrival.

Furthermore, don't miss the opportunity to explore the museum below, offering a wealth of information, including audiovisual presentations, about the Sagrada Família project's history, future plans, and Gaudí himself. You may also want to visit the small school built by Antoni Gaudí for the children of the construction workers right on the site.

Tip:
Please note that children under 6 years old are not permitted to ascend the towers, and the spiral staircase can be challenging for some. If you decide to climb, ask the staff for directions to the "backside elevator", as it is usually less crowded.
