The Eixample, designed by architect Idelfons Cerdà, is made up of an immense mosaic of orderly blocks that make up the centre of the city, in the area outside the city walls. It is divided into left and right hand sides at Carrer Balmes, but the slanting route traced by the Diagonal avenue breaks up the ordered grid framework crossing the whole city from east to west and ending at the sea. In the left hand side of the Eixample, we find the historical building of the University of Barcelona, and the Gran Via is like a tunnel through time that passes through the modernist style Casa Golferichs and reaches the Plaça de les Arenes shopping centre. The right part of the Eixample runs to Passeig Sant Joan and is where the Cerdà plan began. since the Barcelona bourgeoisie abandoned the walled city and began to build small houses with gardens in this area, the only surviving examples of which are to be found in Passatge Permanyer. The area’s neuralgic centres are undoubtedly Plaça Catañunya and Passeig de Gràcia, which are the main focus of the city’s economic activity, the later containing luxury multinational jewelers and fashion stores. Running alongside, another elegant avenue, Rambla Catalunya, is ideal for visitors to have a drink at one of its numerous terrace bars. On the upper side we find the Sagrada Familia neighbourhood, whose name comes from the famous church, Gaudi’s most iconic work.
