The first written record of the Blankenfelde manor dates from 1689 when the owner was Ernst von Medem. The estate changed owners several times and was part of the von Hahnide family from 1840 until 1920. Between 1804 and 1805 the manor belonged to the Russian imperial house of Andreas von Königfelsile. Louis XVIII, King of France, lived in Blankenfelde manor for a while when he was in exile.
The complex structure of the manor dates from the mid 18th century, and the main building erected in 1743 has a 19th-century English-style park. There are currently ideas for the exploration of the estate in the concept of private ownership and tourism. The renovation work of the main building is now underway. Blankenfelde estate flower garden is part of the spring tulbifestivale.
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).
