This district was designed by the architect Cerdá, and was built to connect the old Barcelona (Ciutat Vella) with the surrounding villages. All of the streets here cross in a rectangular style, which is a very unusual design in European town planning. The whole district is built in a Modernist fashion. The most impressive monuments in this district are: some works of Antoní Gaudí, Casa de los Punxes, Plaça de Catalunya, and Paseig de Gracià.
