The Church of Saint Nicholas also called the Saint Nicholas Cathedral is the Baroque church in Lesser Town. It was built between 1704-1755 on the site where formerly stood a Gothic church from the 13th century also dedicated to Saint Nicholas. It has been described as "the most impressive example of Prague Baroque" and "without doubt the greatest Baroque church in Prague and the Dientzenhofers' supreme achievement". It was built by Christoph Dientzenhofer, later by his son Kilian Ignaz Dientzenhofer. The temple excels not only in the architecture, but also in the decoration, mainly by the Jan Lukas Kracker's frescos and inside the 70 m highdome by František Xaver Palko's.
