Château d'Orcher was built to protect the mouth of the River Seine. The square keep was surrounded by a trapezoidal enceinte, defended in the 13th century by three square towers. In 1360 it was partly destroyed on the orders of officials from Harfleur. Rebuilt later, it was taken by the English in 1415 at the same time as Harfleur.
Thomas Planterose took possession of Château d'Orcher in 1735 and over the next ten years set about transforming the castle. He employed master masons François de la Motte and Jacques Lesueur, both from Picardy, and a master plasterer from Caudebec-en-Caux. The elegant woodwork was created by a carpenter Le Roux. The two north towers and the ruins of the great keep in the north-west were demolished, along with the curtain walls. In 1795, following the division of the estate with the death of Madame de Melmont, the property was described as a 'dwelling house castle and accessories and a farm of 145 acres'. In the 19th century, the estate became the property of the Rochechouart family, who had the castle, notably the tower, restored in 1857 by the architect P. Philippon.The castle grounds are open to the public all year. The Château d'Orcher is listed as a monument historique by the French Ministry of Culture. It also includes an imposing square crenellated tower.References:
German crusaders known as the Livonian Brothers of the Sword began construction of the Cēsis castle (Wenden) near the hill fort in 1209. When the castle was enlarged and fortified, it served as the residence for the Order's Master from 1237 till 1561, with periodic interruptions. Its ruins are some of the most majestic castle ruins in the Baltic states. Once the most important castle of the Livonian Order, it was the official residence for the masters of the order.
In 1577, during the Livonian War, the garrison destroyed the castle to prevent it from falling into the control of Ivan the Terrible, who was decisively defeated in the Battle of Wenden (1578).
In 1598 it was incorporated into the Polish-Lithuanian Commonwealth and Wenden Voivodship was created here. In 1620 Wenden was conquered by Sweden. It was rebuilt afterwards, but was destroyed again in 1703 during the Great Northern War by the Russian army and left in a ruined state. Already from the end of the 16th century, the premises of the Order's castle were adjusted to the requirements of the Cēsis Castle estate. When in 1777 the Cēsis Castle estate was obtained by Count Carl Sievers, he had his new residence house built on the site of the eastern block of the castle, joining its end wall with the fortification tower.
Since 1949, the Cēsis History Museum has been located in this New Castle of the Cēsis Castle estate. The front yard of the New Castle is enclosed by a granary and a stable-coach house, which now houses the Exhibition Hall of the Museum. Beside the granary there is the oldest brewery in Latvia, Cēsu alus darītava, which was built in 1878 during the later Count Sievers' time, but its origins date back to the period of the Livonian Order. Further on, the Cēsis Castle park is situated, which was laid out in 1812. The park has the romantic characteristic of that time, with its winding footpaths, exotic plants, and the waters of the pond reflecting the castle's ruins. Nowadays also one of the towers is open for tourists.
