The original structure of Scharfenstein castle was built in 1250. It is suspected that the von Waldenburgs ordered its construction, but only its first owner occupant is known for certain. When, in the 15th century, Greifenstein Castle was destroyed, Scharfenstein also took over the guardianship of Thum, Ehrenfriedersdorf and Geyer. As a result, its value increased, so that in 1439 the Elector acquired the area from the Waldenburgs who were heavily indebted to him. On 26 January 1492 Henry of Einsiedel bought Scharfenstein Castle and its associated villages of Grießbach, Großolbersdorf, Grünau, Hohndorf Hopfgarten and Scharfenstein It remained in the family until 1931.
Following a fire during the night of 1st-2nd June 1921 the entire residential wing and part of the domestic wing was destroyed. From 1921 to 1923 the damaged wings were partially rebuilt to plans by Bodo Ebhardt, based on the old design.
In 1931, a factory owner, Captain Eulitz from Fährbrücke, acquires possession. By his efforts in 1932 in a bird observatory was established. Hundreds of nest boxes were put up throughout the 325 hectares of woodland on the estate; bird-ringing was carried out and scientific reports published, with the support of the Chemnitz Ornithological Society.
In 1945 this forest was seized and made public property, the castle was initially used as the mining school for the state-owned Wismut mining company and, in 1951, a special children's home was established here for maladjusted boys. In 1967, it was converted into a detention centre for juvenile delinquents. Ornithological work was undertaken by the museum at Augustusburg Castle.
In 1993 the castle was taken over by the Saxon Palace Department of the Free State of Saxony. In the period that followed the castle was renovated as a historic monument and converted into a museum. In 1995, on the completion of the renovation work, various exhibitions were opened - and for the first time since 1945, the castle was again open to the public. The bergfried is still used today as an observation tower.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.
