Basilica of SS James the Elder and Agnes the Virgin Martyr was built in the Late Middle Ages. It is one of the biggest Gothic churches in Poland.

There has been a parish church at the site since the first was built between 1195 and 1198.
The current church was built in two phases.
The first stage was built before 1392, when the six-span church was built.
The second stage was built between 1424 and 1430, when the chancel and ambulatory were built.
