his ownership until his death in 1882. 18th-century additions Improvements to Gibside carried out by the Bowes-Lyon family in the 18th and early 19th centuries included landscaping, Gibside Chapel, built between 1760 and 1812, the Banqueting House, a column of Liberty, a substantial stable block, an avenue of oaks and several hundred acres of forest. The top floor of the main house was remodelled as a giant parapet in 1805. The chapel reflects the Calvinist leanings of the family, and though nominally Anglican, the interior is dominated by a huge and centrally placed "three-decker" pulpit. There is a house for the minister/chaplain nearby. Some holders of the position would not have been able to hold a Church of England parish living, on account of their views. The leading Palladian architect James Paine is attributed with most of the work of the 1750s and 1760s. The Banqueting House was built in 1746, and is an early example of Gothic Revival architecture, of the early form often called "Gothick". It has now been restored and is available for letting by the Landmark Trust, who now own it. Column to British Liberty A large monument, originally called the "Column of British Liberty", now usually just the "Column to Liberty", was begun in the 1750s by the hugely wealthy Sir George Bowes, reflecting his Whig politics. Set at the top of a steep hillock, the monument itself is a Doric order column, and topped by a standing bronze female figure, originally gilded, carrying a cap of liberty on a pole. Later history The Bowes-Lyon family had other major country houses, Glamis Castle in Scotland, and Streatlam Castle, County Durham, relatively close to Gibside. The house became vacant in the 1920s after the Bowes-Lyon family sold some of its properties to pay death duties. The building was stripped of its fixtures and fittings, with many of the fireplaces and other items being transferred to Glamis Castle. Parts of the structure were demolished in 1958, including the removal of the roof. What remains is protected by Grade II* listed building status and included in the Heritage at Risk Register. Parts of the grounds have been designated a Site of Special Scientific Interest, including a forest garden. The chapel and Long Walk have been in the National Trust's ownership since 1965, and an additional of the grounds were acquired in 1993. The Banqueting House has been in
