Saint Valentine church in Gdańsk, Gothic church building in Gdańsk, Poland.

Saint Valentine Church in Gdańsk is a parish church in Matarnia, built in the 15th century by Cistercian monks. Its walls show a stone lower section and a brick upper section, evidence of repeated rebuilding. Inside, three 18th-century altars stand in the chancel, and the main altar holds Baroque paintings of Saint Maternus and Saint Valentine.

The church was built in the 15th century by the Cistercian order, replacing an earlier building destroyed during the Thirteen Years' War. Repeated rebuildings left a stone lower section of the walls and a brick upper section. After the order was dissolved in 1831, diocesan priests from Chełmno took over the parish, and the church was renovated in the mid-19th century.

The church is named after Saint Valentine and houses religious artworks inside that remain important to the local community today. These works shape how the space feels and reveal which saints matter most to people who worship here.

The building is open to visitors who wish to attend regular services, held on weekdays and weekends at different times throughout the day. It helps to check the exact times ahead of visiting to plan your trip properly.

Six Gothic tiles were set into the outer wall in the mid-19th century, probably during a renovation. They were later moved inside and built into the baroque-style altar of Our Lady of Perpetual Help in a niche of the right wall.
