A fine example of a regional wooden architecture from the late 15th century, this Roman Catholic Church with rich interiors was added to the UNESCO List in 2003. The church featured a Gothic altarpiece from the early 1500s of which only a venerated figure of Madonna today survives; known as Our Lady of Blizne, the figure was actually being stored in the church attic until a local woman had a vision telling her to retrieve it from the parish priest and create a small shrine in the hollow of a linden tree. There the Madonna racked up miracles until the tree burned down and the figure was eventually returned to the church in the 1970s, where it can now be seen by visitors. The church boasts ample ornamental and figurative wall paintings from the 1500s, including a particularly well-preserved series showing the Passion of Christ, and the illusion of having a coffered ceiling. Guided tours are available if arranged in advance.

Originally the church in Blizne was surrounded by defensive walls, and in 1674 successfully repelled a Tatar invasion, as a nearby shrine upon St. Michael's Hill commemorates. Several other wooden buildings immediately outside the church form a small ethnographic park, including the vicar's house - which predates 1699 and today holds the parish museum, the organist's house from 1866, and a 19th century granary.
