This church is one of the best examples of high baroque north of the Alps. However, K. I. Dienzenhofer's 1711 design didn't have the massive dome that now dominates the Lesser Town skyline below Prague Castle. Dienzenhofer's son, Krystof, added the 78m-high (256-ft.) dome during additional work completed in 1752. Smog has played havoc with the exterior, yet the gilded interior is stunning. Gold-capped marble-veneered columns frame altars packed with statuary and frescoes. A giant statue of the church's namesake looks down from the high altar.
