Monastery church of Saint Francis of Assisi, Romanesque-Gothic monastery church in Na Františku, Prague, Czech Republic.

The Monastery Church of Saint Francis of Assisi in the Agnes Monastery complex is one of its earliest buildings and its most important church. Its original Romanesque-Gothic double nave, with three vaulted bays in each nave, survives only in fragments and was rebuilt in modern times. The main nave adjoined only the south nave, while the convent building stood on the north side.

The convent of the Poor Clares and the Church of St Francis were opened on 25 March 1234, the day the royal daughter Agnes entered the order. The church has an asymmetric two-nave layout with three vaulted bays per nave, mixing late Romanesque and Gothic forms. Under Charles IV the wooden tribune was replaced in stone and a portal was added to the west facade; the church was renovated in 1986.

The church gave its name to the surrounding quarter, Na Františku. Its asymmetric two-nave layout served the Poor Clares, who followed a wooden tribune from their dormitory to hear Mass apart from the public; a portal in the north wall and a window at the triumphal arch still mark it.

The church stands in the Agnes Monastery complex in Na Františku, not on a square.

The church was the last building of the complex to be renovated, in 1986, after the monastery was declared a National Cultural Monument in 1978.

The church gave its name to the surrounding quarter, Na Františku. Its Romanesque-Gothic double nave survives only in fragments and was completed in modern times; it is usually not open to visitors.
