The 96-metre tower, which has become a national symbol since its completion in 1856, has been mostly hidden from view since efforts to restore it began in 2017. The funding required for repairing this magnificent monument is currently estimated to be around £80m.

Conservation work on the 177-year-old structure is supposed to be completed at the end of next year despite the discovery of asbestos, World War-era bombing damage and pollution problems.

In 2017, work began to examine and repair the tower from the gilt cross and orb at its tip to the bottom of its 334-step staircase.

With a 12 square-metre-footprint and a prime location right in the middle of a busy working Parliament, understanding the full extent of the damage to the tower was impossible until the scaffolding was up.

Although the tower survived German bombing during the Second World War, its roof and dials were damaged in an air raid in May 1941 which destroyed the main House of Commons chamber.
