Loreta is a pilgrimage destination in Hradčany. It consists of a cloister, the church of the Lord’s Birth, the Santa Casa and a clock tower with a famous chime. Today the building also houses a large collection of liturgical tools, mainly monstrances. Exhibitions are occasionally held on the first floor of the cloister.
