Daugavgrīva Abbey
Daugavgrīva Abbey or Dünamünde Abbey was a Cistercian monastery in Daugavgrīva in Latvia, about 12 kilometres from Riga, of which Daugavgrīva has formed a district since 1959. The site was re-developed from 1305 as Daugavgrīva Castle.
History
The abbey was founded in 1205 by Albert of Buxhoeveden, bishop of Riga, on the right bank of the Daugava river, and settled by monks from Pforta Abbey, of the filiation of Morimond. The first abbot, Theoderich of Treyden, also known as Theoderich of Estland, had already been active in the mission to Livonia. The second abbot, in the 1210s, was Bernard II of Lippe.The abbey's estates were in part extremely distant. For example, it owned 30 oxgangs of land at Rägelin in Temnitzquell in Brandenburg that had been given to it by the Edler von Plote, on which it ran a farm. During a revolt of the Curonians and Semigallians in 1228 the monks were killed and the monastery destroyed, although soon rebuilt. In 1263 the wooden church was destroyed by a fire. In 1305 the abbey was sold to the Livonian Order, which established its commandery there and converted the site to a fortress, Daugavgrīva Castle or Dünamünde Castle. The monks moved to Padise Abbey in Estonia.
