It is perhaps hardly surprising that Castle Huntly ranks amongst Scotland's lesser known strongholds, despite its great antiquity, when one considers the use to which it has been put since the Second World War. A girl's probationary school, a Borstal for boys, a Young Offenders Institution and currently an Open Prison for adults. Inevitably, accessibility to the general public has been severely restricted and it seldom features in any guidebooks for obvious reasons.
The exact date of construction is uncertain but, in 1452, the first Baron Gray of Fowlis obtained a licence from James II permitting the building of a fortalice on any part of his land and it is generally agreed that Castle Huntly was completed in the second half of the 15th Century. The earliest surviving record, in the "Register of the Great Seal", records a charter granted by James IV, dated at St. Andrews 7th January, 1508, in which the monarch concedes to Andrew, 3rd Baron Gray, then Justiciary of Scotland "the land and barony of Langforgund, with the dependencies, tenants and tenandries-viz, the lands of Langforgund, Huntlie with the tower and fortalice…"
Built by the 1st Lord Gray of Fowlis, Castle Huntly stands on an outcrop of volcanic rock just south from the village of Longforgan. Stone from Kingoodie Quarry, on the banks of the River Tay was used in its construction. Being exceptionally hard stone, it was built to work with but it was extremely durable as evidenced by the condition of the castle building, now nearly 560 years old.
Over the next 200 years there were a number of additions to the castle. In 1660, an additional storey was added by Earl Patrick of Strathmore, in 1776, a major reconstruction was carried out by the Paterson family, when the building was given a new roof, a central tower or "lantern" was added and two wings, each of two storeys, with an entrance hall in between, were erected so forming what is now seen as the front of the castle.
During the war years, the castle was used as a girl's probation school before being purchased in 1946 by the Scottish Home and Health Department for use as a borstal and, today, it still belongs to the Scottish Prison Service.
