The Night of Churches, during which the gates of churches, temples, and prayer houses open during the evening and at night, will take place this coming Friday, May 28. In the 13th year of the event, over 280 buildings will open in the Prague Archdiocese, and more than 1,000 sacred spaces will welcome visitors throughout the country. The theme of this year's Church Night is ecology. The exact conditions of organization and participation in the event will depend on the current government measures against the spread of coronavirus, organizers say. The event has been held in Vienna since 2005. It was probably created by accident when a year earlier a churchgoer left a Viennese church open the door while cleaning and passers-by entered the church with interest. Church Night also takes place annually in Slovakia, Estonia, and, since 2016, Switzerland. This year an app will guide visitors through the program. Visit the Noc Kostelu website for full details.
