Viby was first mentioned in 1331. The current castle was built by Charles IX of Sweden to his wife Kristina between 1622-1626. The Dutch Renaissance style castle was designed by Casper van Panten. After the Crown donated Vibyholm to Gustaf Gustafsson af Vasaborg it has been owned by several families. The castle was left to decay in the early 1700s, but restored by Gustaf Ulf Claesson Bonde af Säfstaholm in the 1730s. The next restorations were made in the early 1800s and between 1852-1854. Today Vibyholm is privately owned and not open to the public.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.
