Church of the Virgin Mary, Former church at Prague Castle, Czech Republic

The Church of the Virgin Mary is a former church inside Prague Castle with an octagonal floor plan rooted in Germanic architectural tradition. It forms part of a protected heritage site and sits within the broader castle grounds, integrated among the other historic structures on the hill.

The building dates to the 14th century, when Emperor Charles IV was shaping Prague into a major European capital and commissioning new religious structures within the castle. The design was led by Matthias of Arras, who set the architectural foundation that later renovations would build upon.

The dedication to the Virgin Mary reflects how central Marian devotion was to court life inside the castle during the medieval period. Visitors who walk through the space can still sense how the layout was designed to serve a community gathered around religious ceremony.

The church sits inside the castle grounds and is reached by following the main visitor paths through the complex. Some sections may be closed at times due to ongoing work, so it is worth checking access on the day of your visit.

The church contains stained glass windows made between 1502 and 1505, added after the original construction was complete, by a later generation of craftsmen. Looking at them closely, you can see how small pieces of colored glass were joined together to control how light enters the space.
