Château de Trémazan was constructed on a rocky outcrop and had a square keep which, following a partial collapse during the winter of 1995, exposed the interior to reveal a habitable tower of four floors, each with one chamber.
The history of Trémazan is intimately linked to that of the du Chastel (or Châtel) family. It was they who built it and made it their principal residence for several centuries. The origins of this dynasty are still shrouded in mist, but with the passage of history, they became very prominent. So much so that Chastels ended up taking their place in the high Breton aristocracy and being counted among the four most important families of the Viscounty of Léon. However, by the end of the 16th century, the elder branch of the family died out for lack of a male heir.
The present castle goes back mainly to the 13th and 14th centuries. The castle would have been built on the ruins of a castellum already existing in the 6th century. According to legend, Tanneguy du Chastel, founder of the abbey at Saint-Mathieu, was born here. The building became a stone castle around the 10th century. In 1220, it was destroyed during the war against the Duke of Brittany, then rebuilt thirty years later by Bernard du Châtel. Sold as national property after the French Revolution, the castle was abandoned in the 18th century. Apart from the 12th century square keep, remains include towers and the outer enceinte dating from the 13th, 14th and 15th centuries.
Today, the non-profit association S.O.S Château de Trémazan attempts to preserve the castle and to increase the knowledge of its past. Thus, samples of the castle beams gave rise to a study of dendrochronology for better dating of the building.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.
