Saint John the Baptist church in Malbork, Gothic church in Malbork, Poland

Saint John the Baptist is a brick hall church with three naves and six bays, built on older foundations and lacking a separate chancel. Its tower was completed in 1623; the main nave has a crystal vault, the side naves ribbed vaults. A Gothic baptismal font from the late 13th or 14th century stands inside.

The first church on this site dates from the late 13th century and was destroyed between 1457 and 1460. Construction of the present brick church began in 1467 on the old foundations and lasted until 1523. The tower was completed in 1623, and after a fire in 1668 the building was shortened by one bay.

Inside, a Gothic baptismal font from the late 13th or 14th century survives, along with a stone Gothic figure of Saint Elizabeth of Thuringia from about 1410 in the south nave. A 17th-century Baroque candlestick carries a Madonna and Child on a deer's antlers, and a panel painting of Solomon's Judgment dates from around 1600.

The church is located in the Old Town district of Malbork and is easily reachable on foot from the city center. Visitors can enter outside of services, but should respect the space as an active place of worship.

During conservation work in 2007, archaeologists found a stone foundation about 6 metres long beneath the brick base east of the church, with diagonal buttresses suggesting a vaulted structure older than the present parish church. A worn stone threshold in the pre-15th-century Wendish bond wall points to the age of the site.
