Built between 1906 and 1912, Casa Milà, commonly known as La Pedrera ('The stone quarry'), is a modernist building in Passeig de Gràcia and the last private residence designed by Catalan architect Antoni Gaudí. Its interior is even more striking than its wrought-iron, stone-carved facade, especially the rooms displaying where people actually lived. So get inside Casa Milà to discover another one of Gaudí's unconventional architectural creations.

The Basilica de Santa Maria del Mar is one of Barcelona’s most stunning churches and a prime example of Catalan Gothic architecture. Its design showcases a cleaner, more restrained style compared to the elaborate ornamentation typically associated with Gothic structures. Construction began in 1329 and was completed in 1383 — an impressive feat for such a monumental project. Inside, the basilica feels remarkably spacious and airy, with its three naves of equal height supported by towering, slender pillars. The sparse decoration of the chapels enhances this sense of openness. Natural light filters through the magnificent rose window on the main façade and the vibrant stained glass windows, bathing the interior in a serene glow.

Founded in 1364, this is one of the oldest universities in Europe, and it can boast names like Nicolaus Copernicus and Pope John Paul II among its alumni. To learn more about the history and campus life, you can take a guided tour. The building is centrally located, close to the Main Market Square.
