Heiligkreuztal Abbey

The origins of Heiligkreuztal Monastery date back to 1140, when a monastic community of Beguines existed in Altheim. These "grey sisters" joined the Cistercian Order in 1204. The official founding of Heiligkreuztal Monastery occurred around 1227. Thanks to the financial support of Count Egon von Grüningen-Landau and his sister Hailwilgilde, who also became the first abbess, a representative monastic building could be erected. The name Heiligkreuztal became established around 1231, allegedly after Count Egon donated a splinter of the True Cross. King Henry (VII) placed the monastery under his special protection in 1234, and Pope Gregory IX confirmed it in 1251 with extensive privileges. Over the centuries, the monastery, which primarily admitted daughters from noble families, acquired extensive possessions. In 1383, the convent comprised 125 women. Abbess Veronika von Rietheim, from 1521, ensured strict monastic discipline and initiated extensive renovations, including the church's decoration by the Master of Meßkirch. The monastery suffered looting during the Schmalkaldic War (1552), by Swedish troops (1632), and French troops (1796). In the course of secularization, Heiligkreuztal Monastery was dissolved in 1802/1803, with the last nuns leaving by 1843.

Heiligkreuztal Monastery is located in the municipality of Altheim, near Biberach, in the Upper Swabia region of Baden-Württemberg. It is situated at an elevation of approximately 551 meters above sea level.

The current appearance of the monastery buildings largely dates from the early to mid-18th century, under Abbess Maria Holzapfel. During this period, stucco work by Joseph Anton Feuchtmayer, an archive of documents, and a significant library were created. From 1973 to 2020, extensive renovation work was carried out on the monastery complex, encompassing the cloister, cells, chapter house, chapel, and other buildings. Notable furnishings include the Christ-John group from the early 14th century in the apse of the church, and a 16th-century cycle of paintings in the cloister.
