Marchtal Abbey is a former Premonstratensian monastery in Obermarchtal in the Alb-Donau-Kreis, Baden-Württemberg, Germany. The minster church of Saints Peter and Paul, the former abbey church, located on a prominent elevation, still dominates the landscape for miles around.HistoryFirst foundationIn 776 the noble clan of the Ahalolfinger made a gift of the monastery founded by their ancestor Halaholf and his wife to St Gall's Abbey. By 993 the monastery had become a collegiate foundation of canons dedicated by Herman II, Duke of Swabia, and his wife Gerberga to the apostles Peter and Paul.During the 12th century the monastery passed through the possession of a series of Swabian nobles, including the Staufen and particularly Frederick I, Holy Roman Emperor. These constant changes of proprietor caused a severe decline in the monastery.Second foundationIn 1171 the monastery was refounded by Pfalzgraf Hugo II of Tübingen as a Premonstratensian double abbey for men and women and given an adequate endowment. The canons were brought from Mönchsrot Abbey in Rot an der Rot. The existing premises were extensive and large-scale construction was not immediately necessary.
