[2] Glamis is set in the broad and fertile lowland valley of Strathmore, in Forfar, county town of Angus, which lies between the Sidlaw Hills to the south and the Grampian Mountains to the north, approximately 20 kilometres (12 mi) inland from the North Sea.

The estate surrounding the castle covers more than 57 square kilometres (14,000 acres) and, in addition to parks and gardens, produces several cash crops including lumber and beef.

An arboretum overlooking Glamis Burn features trees from all over the world, many of them rare and several hundred years old.

John Lyon, 6th Lord Glamis, married Janet Douglas, daughter of the Master of Angus, at a time when James V was feuding with the Douglases.

He began major works on the castle, commemorated by the inscription "Built by Patrick, Lord Glamis, and D[ame] Anna Murray" on the central tower.

[1][2] John Lyon, 9th Earl of Strathmore and Kinghorne, succeeded in 1753, and in 1767 he married Mary Eleanor Bowes, heiress to a coal-mining fortune.

In the 1920s, a huge fireplace from Gibside, the Bowes-Lyon estate near Gateshead, was removed and placed in Glamis' Billiard Room.

[7] On 26 April 1923 she married Prince Albert, Duke of York, second son of George V, at Westminster Abbey.

[1] Since 1987, an illustration of the castle has featured on the reverse side of ten pound notes issued by the Royal Bank of Scotland.

[8] Glamis is currently the home of Simon Bowes-Lyon, 19th Earl of Strathmore and Kinghorne, who succeeded to the earldom in 2016.

[9] The most famous legend connected with the castle is that of the Monster of Glamis, a hideously deformed child born to the family.

[citation needed] An alternative version of the legend is that to every generation of the family a vampire child is born and is walled up in that room.

[12] There is an old story that guests staying at Glamis once hung towels from the windows of every room in a bid to find the bricked-up suite of the monster.

Though this is more likely due to the owners removing them in order so that the guests would not find the rooms, according to several relatives of the family.
