Perched above the Old Town, this Gothic cathedral is Novo Mesto鈥檚 most important historical monument. It has a 15th-century vaulted (and very floral) presbytery and crypt, plus wall frescoes, a belfry that once had been a medieval defence tower, and an altar painting of the church鈥檚 eponymous saint supposedly painted by the Venetian master Jacopo Tintoretto (1518鈥94).
If the church is locked, you鈥檒l find the key at the Provost鈥檚 House (1623), the yellow building to the northwest of the cathedral. Just south of this is a section of the medieval town walls erected in the 14th century.
