Woolwich Cemetery, Kings Highway, Plumstead, London SE18 2DS
The Victorian Woolwich Cemetery comprises essentially two separate cemeteries: the 'old' cemetery, opened in 1856 and accessible through the main gateway off King's Highway, and the newer and larger section which opened in 1885.
All 78,000 of the cemetery's burial records from 1856 until 2000 are now available. As with the other cemeteries within the Royal Borough of Greenwich, the data comprises burial register scans, grave details, cemetery maps showing grave locations and a small number of memorial photographs.
The old section is particularly scenic, built on a hillside with a long driveway sweeping uphill to the original chapel and landscaped with many large and beautiful old trees including cypresses, beech and Scots pine. Among the memorials are three that are particularly notable:
A Celtic Cross paid for by 'National Sixpenny Subscription' from over 23,000 people and erected to the memory of what remains London's worst ever peacetime accident which claimed the lives of approximately 600 people. One of the inscriptions on the memorial describes the accident: "The salon steamer Princess Alice returning from a pleasure excursion was wrecked off Tripcock Point (on the River Thames, near Thamesmead and Gallons Hill) by collision with the steam collier Bywell Castle on the night of September 3rd 1878." Many of the victims were buried in Woolwich Cemetery near to the memorial, including that of the Princess Alice's Captain, William Robert Grinsted, whose family erected a small plain stone memorial nearby.
Another Celtic Cross: "To the memory of Temple Leighton Phipson-Wybrants late Captain 75th Regiment (Gordon Highlanders) who died on his 34th birthday November 29th 1880 while in command of an expedition exploring the Sabi River, Eastern Africa. His body recovered through his mother's devotion October 7th 1881 now rests here".
A WW1 memorial with the names of 14 casualties, which is also surrounded by many other headstones. The cemetery has a total of 175 WW1 burials and memorials.
