The festival gives you the chance to experience architecture in an exceptional way and completely free of charge.

The Open House activities invite everyone to explore and understand the value of a well-built and well-designed building. This event, which originally began in London in 1992, has been held every year in Barcelona since 2010.

For an entire weekend, you can visit dozens of buildings that are usually totally or partially inaccessible to the general public. Over a thousand volunteers organise the queues, the groups and the guided visits. Most of them are architecture students, although they may sometimes be the building's occupants or owners, who become guides for one weekend.

In the fourth edition in 2013, there were a total of nearly 50,000 visitors, 5% more than in the previous year. The most visited location was the Círculo Ecuestre, with 1,900 people, followed by the Antiga Fàbrica Estrella Damm [Old Estrella Damm Brewery] and Palau Moja.
