St. Martin’s Church is a Gothic (Romanesque in origin) church and its south side has been attached to the Castle wall, hence the name ‘in the Wall’. This church was used for residential purposes in the 19th century, and parts of it also served as shops, until it was renovated and re-opened as a church once again around 1905. It has elements of Romanesque, Gothic and Baroque architecture and, though not as grand as some of the other churches of Prague, it has a certain charm.
