Several localities claim to be the area to which the building was moved. The street address of the Crystal Palace was Sydenham (SE26) after 1917, but the actual building and parklands were in Penge. When built, most of the buildings were in the County of Surrey, as were the majority of grounds, but in 1899 the county boundary was moved, transferring the entire site to Penge Urban District in Kent. The site is now within the Crystal Palace Ward of the London Borough of Bromley.
