Erla St. Pantaleon Castle is a historic residence in Sankt Pantaleon-Erla in Lower Austria's Amstetten district, near the Danube River. Originally founded as a Benedictine convent in the 12th century, the complex was dissolved in 1583 and converted into a secular castle. Today, the estate features a two-story residential building with a gabled roof set within the former monastery grounds, which include the historic Parish Church of St. Pantaleon dating to the 11th century. The castle grounds encompass multiple buildings and agricultural lands, reflecting its historical function as a working estate, and represent an important example of the region's blend of religious and secular architectural heritage.
