At no. 6 Paseo de Colón we find the House of Cervantes, where the famous writer Miguel de Cervantes lodged during his stay in Barcelona. The building dates from the 16th century.

In the adjacent square, dedicated to the painter Antonio López, you can find the Central Post Office designed by the architects Goda and Torray (1914). Inside, paintings by Francesc Galí and Josep Obiols decorate the main hall.
