Barcelona is undoubtedly one of the capitals of Europe and the world with most cultural and architectural heritage. Located in a privileged spot of the Mediterranean, strolling through the old town is a delight. Do not miss the Plaça del Rei (King's Square) and all the narrow streets of the Gothic Quarter. And the Paseo de Gracia, the Plaza Catalonia and the Portal de l'Angel, the neuralgic and commercial centre of the city. As well as the modernist architectural heritage left by Gaudí, which has become a universal reference: the temple of the Sagrada Família, the Park Güell, the Pedrera (Casa Milà) and Casa Batlló.
