Due to the coronavirus pandemic, the Open House Prague Festival took place again this year, this time from 2 to 8 August 2021. The weekly accompanying program offered a number of events that introduced architecture to visitors in an unconventional way. People could sail on the Vltava paddle steamer, take the Kotěr tram with an explanation by architect Zdeněk Lukeš, enjoy a unique composed evening with contemporary dance and an evening tour of Laichter's house, or take part in a debate and film screening on abandoned buildings right on the grandstand of the Great Strahov Stadium. There was also interest in the tour and discussion, which presented the course of the reconstruction of Zenger's transformation station, the future headquarters of the Kunsthalle Prague in Klárov. During the week, other guided tours and walks were prepared, for example on the occasion of the 130th anniversary of the Prague Exhibition Grounds, 150 years since the construction of the Gröbe Villa in Havlíčkovy sady or 150 years since the arrival of the first train in Prague. "We were surprised by the great public interest in the accompanying program of the Open House Prague 2021 festival," says director Andrea Šenkyříková, adding: "The events were intended for a limited number of people, and despite the fact that we were already fully booked at the beginning of the festival week.
