Brno boasts many famous architectural jewels, as well as beautiful places to live, experience and return to. Explore the gems that grace this city. Architecture is an art form, strongly influencing our visual perception of the surrounding world. Still, a number of buildings are usually inaccessible and trigger an interest and desire to get in much closer contact with them, get inside and experience the ingenuity of the architect. Open House Brno is a free weekend festival held annually in Brno that allows participants to visit dozens of buildings that are not typically open to the public. Every visit is free of charge. It is part of a worldwide network of Open House events.
