Open House is one of the most important global institutions for the promotion of architecture. The idea began at London in 1992 and until today it has spread to many cities around the globe. The Open House project invites the public to explore and understand the value of architecture. Every year for one weekend, private and public buildings open their gates to everyone for free and the city is transformed to a big museum, with its buildings and architecture being the exhibits. Open House has already taken place for two years in Athens (4-6th April 2014, 15-17th May 2015) with an enthusiastic response from the public. In 2015, 370 volunteers took part in the project, who attended the tours in 68 spaces, while about 20.000 visitors were noted. The third Open House Athens is scheduled for the 15th, 16th & 17th of April 2016.
