Drum Castle in 2007
|Town or city||Drumoak, Aberdeenshire|
|Construction started||13th Century|
|Owner||National Trust for Scotland|
|Design and construction|
|Architect||possibly Richard Cementarius|
The original 13th-century tower of Drum Castle has been suggested as the work of medieval architect Richard Cementarius, who built the Bridge of Don in Old Aberdeen. It is believed to be one of the three oldest tower houses in Scotland (and notably unaltered). A large wing was added in 1619 by the 9th laird, and further alterations were made during the Victorian era.
The castle and its grounds were granted to William de Irwyn in 1325 by Robert the Bruce, and remained in the possession of Clan Irvine until 1975. William de Irwyn (of the Irvings of Bonshaw clan) was armour bearer/secretary (and neighbor) to King Robert the Bruce. In June 1636 Sir Sir Alexander Irvine of Drum and his wife Magdalene Scrimgeour were censured for harbouring the outlaw Gilderoy. Drum played a role in the Covenanting Rebellion (as did nearby Muchalls Castle) leading to its being attacked and sacked three times.
Today, the castle is owned by the National Trust for Scotland and is open during the summer months. The chapel, dining hall and estate may be hired for weddings and corporate functions. A variety of local events such as classic car rallies and musical fetes also occur here. There is also a small shop and tearoom within the castle.
Area ancient history
Prehistoric habitation of the local area is known through archaeological sites such as Balbridie. Roman legions marched from Raedykes to nearby Normandykes as they sought higher ground evading the bogs of Red Moss and other low-lying mosses associated with the Burn of Muchalls. That march used the Elsick Mounth, one of the ancient trackways crossing the Grampian Mountains; the situation of the Elsick Mounth terminating at a ford to the River Dee is thought to have been instrumental in the strategic siting of Drum Castle as a point to monitor traffic on the Elsick Mounth  lying west of Netherley.
