The first sulfur factory in Dylta was mentioned in 1558. It was first owned by the Crown. In 1649 Queen Christina gave mill to Henrik Barckhusen. The Privy Council baron Samuel Åkerhielm became in 1739 the owner of Dylta Mill, which belonged to the family Åkerhielm in 265 years.
The main building, which is built in wood, dates back to the 1740s. In the 1850s, the well-known architect J.F. Åbom designed the Manor House in its present palace-like appearance. The buildings environment is classified as being of national historical interest.
Dylta Bruk is a well-preserved and unique industrial environment with roots in the 16th century, where the passage of time can clearly be perceived. The adjacent Manor House with its farm buildings reinforces the impression of an industrial production deeply rooted in Swedish tradition.
Many buildings and installations bear witness to an earlier, almost 400-year period as a mill. Sulphur was produced on an industrial scale as early as 1583. The production was later supplemented with vitriol, alum and red paint.
Today Dylta offers fishing, hunting and event services.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.
