History+
The origins of the church in Hosterwitz date back to the 12th century, when a wooden church presumably stood there. A pastor was first mentioned around 1406. According to tradition, the current building was erected in 1495 as a late Gothic hall church, donated by Dionysius von Carlowitz, and was named "Maria am Wasser" around 1500. Originally simpler and smaller, it served as a pilgrimage site and a church for fishermen and boatmen. At the end of the 17th century, a Baroque renovation was decided upon, which began in 1704 after a robbery by the Lips Tullian gang in 1702 delayed funding. During the renovation, the church acquired its present form with the added altar area and the onion dome.
