Château de Tancarville was built in the 11th century by Raoul, the chamberlain of Dukes of Normandy. In the 12th century the square tower was built with 1.65m thick walls. In 1418 at the time of the conquest of Normandy by Henry V of England, the title of Earl of Tancarville was given to John Grey. After the Hundred Years War the Harcourt family restored the castle. The ballroom was built in 1468. In 1709 the castle was partially rebuilt by the Count of Evreux. After 1789, the castle was plundered and partly burned. In the 1960s , the castle served as a summer camp for children.References:
The Erfurt Synagogue was built c. 1094. It is thought to be the oldest synagogue building still standing in Europe. Thanks to the extensive preservation of the original structure, it has a special place in the history of art and architecture and is among the most impressive and highly rated architectural monuments in Erfurt and Thuringia. The synagogue was constructed during the Middle Ages on the via regia, one of the major European trade routes, at the heart of the historical old quarter very close to the Merchants Bridge and the town hall. Many parts of the structure still remain today, including all four thick outer walls, the Romanesque gemel window, the Gothic rose window and the entrance to the synagogue room.
After extensive restoration, the building was reopened in 2009. On display in the exhibition rooms is an collection of medieval treasures discovered during archaeological excavations. This includes 3,140 silver coins, 14 silver ingots, approx. 6,000 works of goldsmithery from the 13th and 14th centuries and an intricately worked wedding ring of the period, of which only two others are known to exist anywhere in the world. A mikveh (Jewish bath) has been excavated close by (13th/14th century). The Old Synagogue, the Small Synagogue and two Jewish cemeteries together form a network of historical buildings and sites which vividly portray the role of Jewish life in the history of Erfurt.
