Coombe Hill is a hill in The Chilterns, located next to the hamlet of Dunsmore, Buckinghamshire, England, near the small town of Wendover, and overlooking Aylesbury Vale. It is not to be confused with another Coombe Hill on the flank of Haddington Hill, some two miles (3 km) to the north-east. It is part of the Bacombe and Coombe Hills Site of Special Scientific Interest.
Coombe Hill Monument is one of the first and largest examples of a war memorial erected to honour the names of individual men who fell whilst fighting for their country. The monument is an iconic Buckinghamshire landmark and a Grade II Listed monument.
The monument was erected in 1904, by public subscription, in memory of 148 men from Buckinghamshire who died during the Second Boer War. Coombe Hill Monument was almost totally destroyed by lightning in 1938 and was rebuilt in the same year. The original bronze plaque and decorations were stolen in 1972 and replaced with a stone plaque and iron flag. The new stone plaque was also inscribed with the additional names of nine men believed to have been missing on the original. The monument was again badly damaged by a lightning strike in the early 1990s and spent several months in repair. It is now equipped with conductors to prevent this from happening again. The monument and a few square metres of surrounding land are owned by Buckinghamshire County Council.
