An Augustinian monastery was founded here in 1125 by the Bishop of Hildesheim, Berthold I von Alvensleben, in a place then known as Baccenrode.
In the church, there are two noteworthy baroque altars dating from 1750 approximately and a gothic sandstone sculpture of Saint Mary which was made in 1460.
From 1983, the new Bishop of Hildesheim, Josef Homeyer, was active in the re-establishment of monastic houses.
As a result, Marienrode Priory was re-settled by ten Benedictine nuns from Eibingen Abbey on 5 May 1988.
From the village it can be reached through a tree-lined avenue consisting of 200-year-old lindens, with a historic pavement.
