Holstenshuus estate was first time mentioned in 1314. It is known as Holstenshuus since 1723, whe the estate was acquired by Christian Adolph Holsten. The oldest wing of the current castle was built in 1579 by Knud Venstermand. Two other wings date from 1643. The major restoration was made in 1863-1868 and again in 1910 after a great fire. The surrounding Rococo park (established in 1753) is open to the public.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
