The Baron de Quadras Palace is a modernist building in Barcelona built by the architect Josep Puig i Cadafalch between 1904 and 1906. It stands out for its two facades that combine neo-Gothic and modernist elements, its spectacular stone staircase and modernist rooms. It is currently the headquarters of the Ramon Llull Institute and has been declared a Historic-Artistic Monument of National Interest. A must for lovers of architecture and history.
