Church of St. Klementa

The Basilica of St. Wenceslas was originally a Romanesque church founded in the 11th century, rebuilt in Renaissance and Baroque style. The church suffered greatly during the Hussite wars, but the services were not interrupted. Basic repairs were carried out in the middle of the 15th century. The basilica was not significantly rebuilt in the Renaissance style until the end of the 16th century. In the years 1639-1640, the Swedish army built a camp in Stará Boleslav, the north tower was demolished and the church was burnt down during the retreat of the Swedes. The chapter began with the immediate restoration of the basilica but continued in the early Baroque style after the end of the war.

The Church of the Assumption of the Virgin Mary was founded at the beginning of the 17th century and is the oldest Marian pilgrimage site in the Czech Republic. The present church replaced the older Gothic building, which was not big enough for the growing number of pilgrims. It was built according to the plans of the Italian architect Giovanni Maria Filippi, under the direction of Jakub de Vaccani in the years 1613-1625, in the style of early Baroque Roman churches.

Its foundation stone was laid in 1854 in the presence of Emperor Francis Joseph I, a tribute to the support of the Habsburg monarchy by the First Congress of Panslav in Prague as a political formation that is most likely to protect the peoples of Central Europe.
