During the Commonwealth of England, Scotland, and Ireland, soldiers were garrisoned at Glamis. In 1670, Patrick Lyon, 3rd Earl of Strathmore and Kinghorne, returned to the castle and found it uninhabitable. Restorations took place until 1689, including the creation of a major Baroque garden. 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. He set about improving the grounds of the castle in the picturesque style in the 1770s. The south-west wing was rebuilt after a fire in the early 19th century. In the 1920s, a huge fireplace from Gibside, the Bowes-Lyon estate near Gateshead, was removed and placed in Glamis' Billiard Room. The fireplace displays the coat of arms of the Blakiston family; Gibside heiress Elizabeth Blakiston had married Sir William Bowes. Several interiors, including the Dining Room, also date from the 18th and 19th centuries.
