The ruins of the collegiate church lie on a peninsula near Bremm on the Moselle. The site of the former monastery is used for viticulture and has become known as a single location through the brand "Abtei Kloster Stuben".
The foundation of the monastery at the beginning of the 12th century goes back to the Augustinian canons of Springiersbach. At the request of his daughter Gisela, the nobleman Egelolf gave Abbot Richard I of Springiersbach his castle house, a chapel and other properties on a headland near Bremm to build a monastery - a donation that enabled him to have a St. Nicholas Church built. Stuben is first mentioned as ecclesia beati Nicolai de insula, around 1160 as sorores de Insula. In 1137 a large women's convent settled here. The Trier Archbishop Albero limited this to 100 women in his founding confirmation from 1137. In 1208, the knight Henry of Ulmen (provably 1202-1236) gave his sister Irmgard of Ulmen, as head of the monastery, the storage library (today in the Diocesan Museum of Limburg an der Lahn) with cross particles and other relics that he had collected from the Fourth Crusade (1202-1204). Constantinople had brought with him. Since then, Stuben has attracted many pilgrims. A cross chapel was built around 1275 to venerate the relic. Despite the economic decline, the monastery church and cross chapel were rebuilt between 1685 and 1687. In 1788 the monastery was converted into a free women's monastery, but was abolished in 1802. The monastery buildings were auctioned off for demolition in 1820.
The Staurothek and other relics were brought to the right bank of the Rhine as part of the escape from the French. It came to the Duke of Nassau-Weilburg, who donated it to the newly founded Diocese of Limburg in 1835 along with other Trier relics (including the Staff of Peter).
