Kilian Ignaz Dientzenhofer

Kilian Ignaz Dientzenhofer (Czech: Kilián Ignác Dientzenhofer) (1 September 1689, Prague – 18 December 1751) was a Bohemian architect of the Baroque era. He was the fifth son of the German architect Christoph Dientzenhofer and a Bohemian (Czech) mother and a member of the well known Dientzenhofer family of architects. As an architect he co-operated with his father and with Jan Santini Aichel.

Among Dientzenhofer's buildings are the Church of St. John of Nepomuk, the Church of St. Nicholas, and the Vila Amerika and Goltz-Kinsky Palace in Prague. He also built numerous churches and secular buildings in other towns of Bohemia. Many of his later projects were realized by his pupil and son-in-law Anselmo Martino Lurago.
