Kaple svaté Máří Magdaleny pod Letnou, Baroque chapel in Holešovice, Prague 1, Czech Republic.

The Kaple svaté Máří Magdaleny pod Letnou is a circular early Baroque chapel built in 1635 by Jan Dominik de Barifis on the Cyriac monastery vineyard. It stands on a massive stone-clad base near the Vltava, and its six windows hold stained glass by Alena Novotná-Gutfreundová depicting scenes from its history.

The chapel was built in 1635 as a prayer site for vineyard workers and raftsmen who faced hazardous conditions on the river. Over the centuries it became an established place of worship for the surrounding community.

The chapel serves as a place of worship for multiple congregations and welcomes visitors throughout the day. People come here to pray and experience a moment of quietness in the middle of the city.

The chapel is located at the base of Letna Park and can be reached by tram at the Čechův most stop nearby. The site is easily accessible on foot from the city center and sits along walking paths that follow the river.

The chapel was moved 31 metres upstream along the Vltava on 3 and 4 February 1956, saved by a method devised by Professor Stanislav Bechyně when the Letná embankment and the Čechův Bridge approach were rebuilt. Its six windows hold stained glass by Alena Novotná-Gutfreundová showing the vintage harvest, raftsmen resting, the Swedes in Prague, the bridge's construction, the wall reinforcement and the move itself.
