Church of the Assumption of the Virgin Mary

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 Romanesque church of St. Klementa is located in the immediate vicinity of the Basilica of St. Wenceslas. It is the oldest building of Stará Boleslav, which has been preserved until today in an almost unchanged form and belongs to the oldest church buildings in the Czech lands. The church acquired its present form in the third quarter of the 12th century, but it is an older foundation dating from the 11th century, which was preceded by a wooden building possibly dating from the 10th century.

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.
