Aggsbach Charterhouse is a former Carthusian monastery in Aggsbach Dorf. The monastery was founded in 1380 by Heidenreich von Maissau. It was dissolved in 1782 in the reforms of Emperor Joseph II. The premises were mostly converted for use as a castle, except for a few portions which were incorporated into the parish priest’s farm. The monks’ cells and the cloister were demolished. The Carthusian church, with the addition of a tower, remains as the parish church.
