You will get better acquainted with the pilgrimage and spiritual story of Brezje in the museum of votive offerings and nativity scenes that lies adjacent to Brezje's basilica. The creativity captured in the votive offerings on display, such as gifts and pilgrims' personal messages and wishes, as well as the nativity scenes made from a variety of materials that originate from around the world can be seen in the museum.

The name Canticle of the Sun Museum derives from a religious song composed by Saint Francis of Assisi. The museum holds two complementary collections: the first, which comprises preserved votive offerings, testifies to Brezje's rich pilgrimage tradition, while the second collection testifies to the tradition and variety of the nativity scenes of Slovenia and the rest of the world.
