Saint Sigismunt Church in Szydlowiec is a church that was built towards the close of the Gothic period and is an example of the Late Gothic hall church. The exterior is of local sandstone. The late-Gothic silhouette of the church does not prepare a visitor for the impression made by its Renaissance interior colorful polychromy.
There are a lot of original monuments: gravestone of Mikołaj Szydłowiecki, gravestone of Mikołaj Radziwiłł and his wife Maria née Gawdzicka and was inspired by sleeping Ariadna's. In the chancel there is a most beautiful late-Gothic polyptych showing the Assumption and Evangelical scenes made in 1509 in a workshop in Kraków. The 19th-century church organ of the beautiful and rich tone are used also for secular purposes within the framework.
