1852, his place as Knight of the Garter was given to Londonderry, who was officially invested on 19 June 1853. Death, memorials, and succession He died on 6 March 1854 at Londonderry House and was buried in Longnewton, County Durham. His widow honoured him by the Londonderry Equestrian Statue in Durham. Frederick built Scrabo Tower near Newtownards as a monument to the memory of his father. Of the 730 subscribers to the cost, just 450 were connected to the Stewart estate on which there were 1,200 tenants farmers and many associated employees (in 1850, organised in the all-Ireland Tenant Right League, 700 of these tenants had signed an address demanding tenant right and lower rents). Two-thirds of the cost of the tower was met by 98 subscribers (in a list headed by Emperor Napoleon III) most of whom were fellow gentry.* He was succeeded as Marquess of Londonderry by his eldest son, Frederick Stewart, the only child from his first marriage, and as Earl Vane by George Vane, the eldest son from his second marriage. At Charles's death Frederick, therefore, became the 4th Marquess of Londonderry, whereas George became the 2nd Earl Vane. George was later to become the 5th Marquess after his half-brother had died childless. Styles Charles was styled: The Honourable Charles Stewart from 1789 until 1813 (because his father was created Baron Londonderry in 1789), The Honourable Sir Charles Stewart from 1813 to 1814 (because he was made a Knight of the Bath), The Right Honourable The Lord Stewart from 1814 to 1822 (because he was made a baron in his own right) The Most Honourable The Marquess of Londonderry.
