Ale's Stones (Ales stenar) is a megalithic monument which consists of a stone ship 67 meters long formed by 59 large boulders of sandstone, weighing up to 1.8 tonnes each. According to Scanian folklore, a legendary king called King Ale lies buried there.
The carbon-14 dating system for organic remains has provided seven results at the site. One indicates that the material is around 5,500 years old whereas the remaining six indicate a date about 1,400 years ago. The latter is considered to be the most likely time for Ales Stenar to have been created. That would place its creation towards the end of the Nordic Iron Age.
In 1989, during the first archaeological excavations performed in order to scientifically investigate and date the monument, archaeologists found a decorated clay pot with burned human bones inside the ship setting. The bones are thought to come from a pyre and to have been placed in the pot at a later date. The pot's contents varied in age; some material was from 330-540 CE while a piece of charred food crust also found inside was determined to be from 540-650 CE. The archaeologists working on the project also found birch charcoal remains from 540-650 CE underneath an undisturbed boulder. According to the Swedish National Heritage Board, carbon-14 dating of the organic material from the site indicates that six of the samples are from around 600 CE, while one sample is from ca. 3500 BCE. The diverging sample came from soot-covered stones that are believed to be the remnants of an older hearth, found close to the ship setting. On the basis of these results, the Swedish National Heritage Board has set a suggested date of creation for Ales Stenar to 1,400 BP, which is the year 600 CE.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.
