The Kirche Zur Heiligsten Dreifaltigkeit in Vienna, better known as the Wotruba Church, is located on the Sankt Georgenberg in Mauer in Liesing, the 23rd District of Vienna. It was built between August 1974 and October 1976 on the basis of a model by Fritz Wotruba.
Wotruba died before the completion of the church, which was inspired by a visit to Chartres Cathedral. To Wotruba, Chartres represented the essence of Europe, and Wotruba subsequently held up Chartres as a yardstick to his own work. Wotruba was first and foremost a sculptor, and the church was a collaboration with Fritz G. Mayr, who continued the work after Wotruba's death.
