Saint Giles Church, Nymburk, Gothic brick church in Nymburk, Czech Republic.

Saint Giles Church is a Gothic brick building in Nymburk with a prominent front tower reaching 66 meters high. The structure features pointed arch windows and carefully crafted ribbed vaults that run throughout the interior.

The building began as a church dedicated to Saint Nicholas in the 13th century. It received its current name, Saint Giles, during the turbulent period of the Thirty Years War.

The church was originally dedicated to Saint Nicholas and only received the dedication to Saint Giles during the Thirty Years' War. A memorial plaque at the north entrance recalls the 1634 massacre, and that portal has remained permanently closed since then.

The church stands on Kostelní náměstí in the town centre, with a paved square now surrounding it where the cemetery once lay. The north portal has been walled shut since the 1634 massacre and is not used; the red tower was reduced in 1846 and survives only to the level of the main nave cornice.

The north portal has been walled shut since 16 August 1634, when Saxon troops entered the church through it and killed more than 200 townspeople hiding inside; a memorial plaque by the north entrance recalls the massacre.
