The Church of St Francis represents a type of a Gothic monastic church, characterised by its single-nave space with an elevated Sanctuary. In the Treasury next to the famous Sacristy there is an art collection with a big number of artefacts on display, the most valuable of which is the painted wooden Crucifix from the 12th century. In the south of the Church there is a Renaissance cloister that was built in 1556 together with a rich Library.
