The Royal Hospital, Greenwich (now the Old Royal Naval College) face a problem in the 1840s: its burial ground was full. Despite the name, that didn't suggest poor medical care. The Hospital provided a home for several thousand Navy pensioners who were either elderly or infirm, so most of its residents would expect to die there. They were buried around Devonport House, then the infirmary.
After spending quite a while searching for a suitable site for a new location, the Admiralty bought this land in 1857. Within a few decades, the original burials in central Greenwich were threatened by a railway tunnel, so a further 3,000 burials were moved here. More were relocated in 1925 to enable a nurses' home to be built. There are other maritime burials too, including Greenwich staff and naval First World War graves.
One which does not appear to fit here is the grave of Anthony Francis Oscar Sampayo, Minister Plenipotentiary (ie ambassador) of France, who died on 4 August 1862. However, the Standard death announcement discloses the reason for his presence: he died 'at the residence of his uncle, Sir W. Cunningham Dalyell, Bart., Royal Navy, Greenwich Hospital'. Cunningham Dalyell was in fact commander of the hospital, and was married to Maria Sampayo. Her brother (presumably Anthony's father) was French Minister at the German state of Hesse Cassel, a post held by Anthony at the time of his death.
A year after the 1925 reinterments, the cemetery was sold to the Borough of Greenwich and became a park. Today, it has a cafe and play areas; visitors stroll or play among the gravestones.
