Dagstuhl Castle ruins overlooks the newer Schloss Dagstuhl in the valley below, which is historic but has been converted for use as a conference centre. The castle was founded by Knight Boemund of Saarbrücken sometime before 1290, probably for Bohemond I von Warnesberg, Archbishop of Trier. The name derives from the German word for roof, 'Dach', because of the roof-like shape of the hill on which the castle stands.The castle ruins have been archaeologically explored and were improved for public access in 2004.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.
