it a strategically advantageous location for a fort. In March 1644, during the First English Civil War, the hill served as an encampment for an army of Scottish Covenanters who fled there after a failed attack on Newcastle before the Battle of Boldon Hill. The hill is associated with the local legend of the Lambton Worm; a folk song written by C. M. Leumane in 1867 describes the worm wrapping itself "ten times roond Pensha Hill". The hill is the site of an 18th-century limestone quarry on Dawson's Plantation, which is a designated Site of Special Scientific Interest; farming and quarrying on nearby land continued after the monument's construction. The landholding is on the north-eastern edge of the historical township of Penshaw; the original village of Old Penshaw is approximately from the monument. After Penshaw Colliery opened in 1792, a new pit village was established to the south-west of the original village – it was known as New Penshaw. The earliest record of Penshaw is in the Boldon Book of 1183, where it is described as being leased by William Basset from a Jordan de Escoland, later Jordan de Dalton. Other former landowners of the vill include the Bowes-Lyon and Lambton families. The land on which the monument stands was eventually passed to the Vane-Tempest-Stewart estate and became the property of Charles Vane, 3rd Marquess of Londonderry, who gifted it as the site of the structure.

He resigned his position in 1833, and was created Earl of Durham shortly afterwards. He was a Freemason and became Deputy Grand Master of the United Grand Lodge of England in 1834. The second Melbourne ministry appointed him Ambassador to Russia in 1835; he spent two years in the post. In 1838 Durham agreed to become Governor-General of British North America, and was sent
