On Friday, June 7, the annual Night of Churches begins, during which you can explore the interiors of several hundred churches and prayer rooms across the Czech Republic, including Děčín and its surroundings. For example, you can visit the Church of the Holy Trinity in Dolní Žleb, where the Saxon Mountaineering Choir Kurt Schlosser from Dresden will be performing a concert. The Thun Chapel in Děčín also offers a cultural program (information here).
