overview opening hours about the place This monumental three-aisled church was built on the foundations of a Romanesque church from the 14th century. In 1625 the church was donated to the Dominican order, which has served here and in the adjacent monastery ever since. The church was remodelled in Baroque style. The frescoes decorating the interior are by Wenzel Lorenz Reiner, who was one of the leading Czech Baroque painters and whose remains are interred here. more about the place opening hours november—march mon, tue, wed, thu, fri, sat, sun 10:00—16:00 april—october mon, tue, wed, thu, fri, sat, sun 08:00—18:30 more about opening hours Source: praha.op.cz opening hours november—march mon, tue, wed, thu, fri, sat, sun 10:00—16:00 april—october mon, tue, wed, thu, fri, sat, sun 08:00—18:30 Regular Roman Catholic Masses Mo – Su 18.30 – in Czech Su 9.00 – in Czech,10.30 – in French, 12.00 – in Polish Sightseeing possible from behind the grid in foyer or just after the mass, large groups by telephone appointment only.
