The parish church — formally the church of Saints John the Baptist and Bartholomew — sits just up from the market square and is the oldest building in town still in active use. The current Renaissance/Mannerist structure dates from the early seventeenth century, although a church has stood on the site since the fourteenth.
The interior is unexpectedly grand for a small-town parish: a richly stuccoed barrel vault, a sequence of side chapels with carved altarpieces, and one of the oldest organs in Poland, from 1620 (still playable, occasionally used for evening concerts). Worth a few minutes in passing, and ask in the sacristy whether a recital is on.
