Czech Baroque architecture refers to the architectural period of the 17th and 18th century in Bohemia, Moravia and Silesia, which comprised the Crown of Bohemia and today constitute the Czech Republic.
The Baroque style also changed the character of the Czech countryside (churches and chapels in Czech countryside are mostly Baroque). Czech Baroque architecture is considered to be a unique part of the European cultural heritage thanks to its extensiveness and extraordinariness. In the first third of the 18th century the Czech lands (especially Bohemia) were one of the leading artistic centers of the Baroque style. In Bohemia there was completed in a very original way the development of the Radical Baroque style created in Italy by Francesco Borromini and Guarino Guarini. The leading architects of the Czech High Baroque style (also called Radical Baroque of Bohemia) were Christoph Dientzenhofer, Kilian Ignaz Dientzenhofer and Jan Blažej Santini-Aichel.
