Christoph Dientzenhofer (born July 7, 1655, Rosenheim, Bavaria [now in Germany]—died June 20, 1722, Prague, Bohemia, Austrian Habsburg [now in Czech Republic]) was a German architect who was a leading builder in the Bohemian Baroque style.
Dientzenhofer was a member of a large family of German architects and father of Kilian Ignaz Dientzenhofer. The two worked together on the Church of St. Nicholas (1703–11, 1732–52) and the Břevnov Monastery (1708–21), both in Prague.
