Now in its fifth year, 48h Open House BCN forms part of the worldwide Open House initiative, which seeks to open up outstanding architecture for all to experience and to encourage dialogue about urban space.
For two days visitors get the chance to take a look inside over 150 buildings around the city. These range from apartments on Pg. de Gràcia to hotels, schools, libraries, shops and private homes and encompass Roman ruins to contemporary architecture, Catalan gothic, neoclassic, modernist and modern. Architects and volunteers will be on hand to offer more information about the buildings.
Although entry to every building is free, anyone who doesn't feel like queuing (inevitable in some of the most popular buildings) can buy a pass that gives them priority entrance (€35 for a day or €50 for the weekend).
