Golders Green Crematorium and Mausoleum was the first crematorium to be opened in London, and one of the oldest crematoria in Britain. The land for the crematorium was purchased in 1900, costing £6,000, and was opened in 1902 by Sir Henry Thompson.
The crematorium, the Philipson Family mausoleum, designed by Edwin Lutyens, the wall, along with memorials and gates, the Martin Smith Mausoleum, and Into The Silent Land statue are all Grade II listed buildings. The gardens are included in the National Register of Historic Parks and Gardens.
Golders Green Crematorium, as it is usually called, is in Hoop Lane, off Finchley Road, Golders Green, London NW11, five minutes' walk from Golders Green tube station. It is directly opposite the Golders Green Jewish Cemetery (Golders Green is an area with a large Jewish population). The crematorium is secular, accepts all faiths and non-believers; clients may arrange their own type of service or remembrance event and choose whatever music they wish.
