All Saints' Abbey, Monastery ruins in Black Forest, Germany

All Saints' Abbey consists of stone ruins situated at 620 meters elevation in a forest valley of the Black Forest region. The site features a museum, shop, and chapel that visitors can explore among the remaining structures.

Duchess Uta of Schauenburg issued the foundation charter around 1196, confirmed by Emperor Henry VI; Philip of Swabia recognised it in 1200 and Pope Innocent III in 1204, with Gerung as first abbot. Canons from All Saints reformed Lorsch Abbey in 1248, making it a daughter house, and another was set up at Haguenau. A fire destroyed the monastery in 1470; it was raised to abbey status in 1657 and dissolved in 1802 by Margrave Karl Friedrich of Baden.

The monastery's name comes from its dedication to All Saints, and its church held altars and saints' figures that were later moved to parish churches in Bad Peterstal, Oppenau, Ottenhöfen and Achern. Three statues from the abbey — Saint Helena, Uta of Schauenburg and the first abbot Gerung — stand above the gateway of the prince's chapel at Lichtenthal Abbey. Since 1960 a chapel on the site, like the abbey church, is dedicated to All Saints.

The ruins stand at 620 metres in the upper Lierbach valley, reached on foot; sturdy shoes help on the forest paths. The All Saints' Waterfalls lie directly below the site, and a café and small museum are on the grounds. A war memorial for members of the Schwarzwaldverein, raised in 1925, stands on the rise above the ruins.

The founder was Duchess Uta of Schauenburg, not a man. According to the foundation legend, she tied a bag of gold to a donkey and let it roam; it dropped the bag at the remote site where she then built a wooden chapel, later expanded into the monastery.
