Naumburg Castle (Erbstadt)

The Cyriakus Monastery of Naumburg was first mentioned in 1035 as "castello Nuwenburg". Originally dedicated to Saint Cyriacus, and later to the Holy Cross, the property was transferred by Henry IV to Bishop Rüdiger Huzmann of Speyer in 1086. His successor, Günther von Henneberg, handed over the already existing Benedictine provostry to Limburg Abbey on the Haardt in 1149. The monks, often from noble families of the Wetterau, ensured the monastery's good material endowment, with its most significant relic being a splinter from the wood of Christ's cross. From the 13th century, the Lords and Counts of Hanau exercised guardianship over the monastery. After destruction during the War of the Landshut Succession, the complex was rebuilt in 1505, this time under the spiritual authority of Seligenstadt Abbey.
