The street address of the Crystal Palace was Sydenham S.E (SE26 after 1917), but the actual building and parklands were in Penge. At the time of relocation most of the buildings were in Croydon, as were the majority of grounds. 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.
