Sir Charles Reed Peers CBE FRIBA FSA (22 September 1868 – 16 November 1952) was an English architect, archaeologist and preservationist. After a 10-year gap following the death of Lieutenant-General Augustus Pitt Rivers in 1900, Peers became England's second Inspector of Ancient Monuments from 1910 and was then the first Chief Inspector of Ancient Monuments from 1913 to 1933.
Peers was born in Westerham in Kent, the eldest son of an Anglican clergyman. He was educated at Charterhouse School and studied classics at King's College, Cambridge from 1887 to 1891, graduating in the second class and then continuing his studies in Dresden and Berlin.
From 1893 to 1896 he worked as a pupil architect in the office of Thomas Graham Jackson. He spent a season with archaeologist George Somers Clarke in Egypt in 1896, and then returned to England to practise as an architect. He was editor of The Archaeological Journal from 1900 to 1903.
After visiting Egypt again in 1902, he became architectural editor of the Victoria History of the Counties of England in 1903, supervising the architects that described and drew plans of the buildings included in the volumes. Peers himself drew the plans and wrote the descriptions for a number of buildings, including Winchester Cathedral and St Albans Abbey.
