Bolków Castle is located in Bolków on the Castle Hill (Wzgórze Zamkowe), with a 396 metres, where the hillside is cut by the Nysa Szalona river, with a sharp precipice (with a sudden drop of 90 metres); the eastern side of the hill gradually lowers, taken up by the town. The castle is an upland stronghold, covering an area of 7600 m².
First mentions of the castle come from 1277, from the time of the reign of Boles³aw II Rogatka, Duke of Legnica. The castle's current shape was only done so by various constructions in the sixteenth century, the famous Silesian architect Jakub Parr brought elements of the Renaissance into the castle's fortifications. After the construction and expansion, the castle had a total area of 7600 m², making it one of the largest castles in Silesia. In 1703, the castle in Bolków was bought by Cistercian monks from Krzeszów. After the laicisation of monastic property, the castle went to the State Treasury of Poland.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.
