Saint Walpurga
The town remained a possession of Oettingen until the end of the "Landshut war of succession" in 1505. Monheim was then handed to the duchy Palatinate-Neuburg (German: "Pfalz-Neuburg"), whom it remained with until 1808. The duke Heinrich introduced the Reformation to his lands and Monheim in 1530 and the convent in town was dissolved. Monheim lost its relics and with it much of its religious importance for the region. The convent building was taken down in 1574 but the large Saint Walpurga church, the current building dating from 1509, and some of the convents Romanesque courtyard, dating from the 12th century, remained. The courtyard was fully restored in 1977.
