Crucuno dolmen is one of the most well known dolmens in the Brittany. The rectangular chamber is about 4 metres by 3.5 metres, covered by a single massive capstone which measures over 7 metres in length, perched on top of 9 support stones, with easily enough room to stand upright inside. The enormous capstone is 7.6 metres in length and weighs about 40 tons. Unfortunately, a century or so ago, a house was built right next to it, and this has destroyed all but the last pair of entrance passageway uprights and their capstone. This passageway was recorded in the last century as being 20-25 metres in length, leading away towards the southeast.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.
