Glamis Castle is situated beside the village of Glamis in Angus, Scotland. It is the home of the Earl and Countess of Strathmore and Kinghorne, and is open to the public. Glamis Castle was the childhood home of Elizabeth Bowes-Lyon, best known as the Queen Mother. Her second daughter, Princess Margaret, was born there. Since 1987 an illustration of the castle has featured on the reverse side of ten pound notes issued by the Royal Bank of Scotland. The plasterwork ceilings of Glamis are noteworthy for their detail and preservation.

Glamis is set in the broad and fertile lowland valley of Strathmore, near Forfar, county town of Angus, which lies between the Sidlaw Hills to the south and the Grampian Mountains to the north, approximately 20 kilometres inland from the North Sea. The estate surrounding the castle covers more than 14,000 acres (57 km²) and, in addition to the garden containing lush gardens and walking trails, produces several cash crops including lumber and beef. The two streams run through the estate, one of them the Glamis Burn. An arboretum overlooking Glamis Burn features trees from all over the world, many of them rare and several hundred years old. Birds and other small wildlife are common throughout the grounds.

The most famous legend connected with the castle is that of the Monster of Glamis, a hideously deformed child born to the family. In the story, the monster was kept in the castle all his life and his suite of rooms bricked up after his death.Another monster is supposed to have dwelt in Loch Calder near the castle. 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. 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. When they looked at it from outside, several windows were apparently towel-less. The legend of the monster may have been inspired by the true story of the Ogilvies.

If you stand outside the castle and count the number of windows, and compare them with the number of windows inside the building, you will always be two windows short; in other words, there seems to be a walled-up secret room in Glamis, and what this room contains has been the subject of much debated for over 600 years. Some say it is on the top story of the castle inside a tower. Then there is another clue; one of the Earls of Strathmore said he once overheard King James V mentioning the thing locked up in its room. Many servants at the time speculated that the 'thing' was a deformed overgrown child. This maybe for in an oil painting at the castle, there is a strange green-clad figure of a child with a strangely-deformed torso. The identity of the painting's subject has never been established.

A prominent Edinburgh lawyer was driving to Glamis on a visit a few years ago, he and some friends had been invited to dinner there. As they drove into the castle grounds they saw the shadowy figure of a woman dressed in white. To their astonishment she glided along so swiftly she kept pace with the car-and accompanied them right up to the castle doors. Then she vanished. At first they thought she was one of the maids out for an evening stroll. But they were soon informed that all the maids were indoors that night. However, because of the strange appearance of the woman and the speed and manner with which she had moved, the lawyer admitted that he believed she had been a ghost.
