Down House is the former home of the English naturalist Charles Darwin and his family. It was in this house and garden that Darwin worked on his theories of evolution by natural selection which he had conceived in London before moving to Down. The house stands in Luxted Road 0.25 miles (0.40 km) south of Downe, a village 14.25 miles (22.93 km) south east of London's Charing Cross, which was still known as Down when he moved there in 1842. In Darwin's day, Downe was a parish in Kent: it subsequently came under Bromley Rural District, and since 1965 has lain within the London Borough of Bromley.
