Church Of St. Martin In The Wall (Kostel sv. Martina ve zdi)
Address: Martinská, Praha 1

Marking the boundary between the Old Town and the New Town, its name dates from the time when the church was a part of the town wall during the fortification of the Old Town. Originally a Romanesque building it was renovated in Gothic style twice. During the Hussite Movement in 1414, it was this church where communion was offered for the first time to everyone, not only priests.
