Archeological investigations have shown that the Lauterstein castle was built in the second half of the 12th century. It was first mentioned in writing in 1304 when a document named a Johannis in Lutirstein of the ministerial family of Erdmannsdorf in the castle. Its purpose was the protection of a medieval trade route between Leipzig and Prague across the Ore Mountains.
The family of Schellenberg became lords of Lauenstein in the early 14th century. They lost their influence in 1323 after they lost a feud with Altzella Abbey, and margrave Frederick the Brave enfeoffed the burgraves Albrecht IV von Altenburg und Otto I von Leisnig, who had helped to support him and the abbey, with Lauterstein castle and the town of Zöblitz.
Kaspar von Berbisdorf from Freiberg, an owner of mines and metalworks in the Ore Mountains, bought the lordship of Lauterstein for 4000 guilders from burgrave Otto II of Leisnig and Altenburg in 1434. His descendants Bastian and Melchior divided the lordship and the castle in 1497 into Oberlauterstein and Niederlauterstein. A fire damaged the castle in 1530, but it was rebuilt within a few years. In 1559, Prince-elector Augustus forced the Berbisdorf family to sell castle and lordship Lauterstein for 107,784 guilders and installed the administration of a Saxon Amt in the castle.
According to local tradition, on 14. March 1639, three Swedish horsemen set fire to the castle. It was not rebuilt and has remained a ruin since then. The administrative seat of Amt Lauterstein moved to Marienberg and later to Olbernhau and Zöblitz.References:
Easter Aquhorthies stone circle, located near Inverurie, is one of the best-preserved examples of a recumbent stone circle, and one of the few that still have their full complement of stones. It consists of a ring of nine stones, eight of which are grey granite and one red jasper. Two more grey granite stones flank a recumbent of red granite flecked with crystals and lines of quartz. The circle is particularly notable for its builders' use of polychromy in the stones, with the reddish ones situated on the SSW side and the grey ones opposite.
The placename Aquhorthies derives from a Scottish Gaelic word meaning 'field of prayer', and may indicate a 'long continuity of sanctity' between the Stone or Bronze Age circle builders and their much later Gaelic successors millennia later. The circle's surroundings were landscaped in the late 19th century, and it sits within a small fenced and walled enclosure. A stone dyke, known as a roundel, was built around the circle some time between 1847 and 1866–7.
