Inside the fortress lies the old Protestant burying-ground, with tombs of Sackville, of John Murray, of Sir Francis Vincent, last ambassador but one from Great Britain to the republic, of Consul Smith, whose collection of books forms the nucleus of the King's library in the British Museum, and of Catherine Tofts, the singer, Smith's first wife.
The old burying-ground was the kirkyard of the former parish church, the tower of which still exists, but a modern cemetery has been formed in Sunnyside.
A burying-ground has also extended itself over a large tract of land, formerly occupied by the streets of the city.
To the three named should be added the Calton burying-ground, with its Roman tomb of David Hume, and the obelisk raised in 1844 to the memory of Maurice Margarot, Thomas Muir (1765-1798), Thomas Fyshe Palmer (1747-1802), William Skirving and Joseph Gerrald (1765-1796), the political martyrs transported towards the end of the 18th century for advocating parliamentary reform.
An Eliot monument was erected in 1847 on the Indian burying-ground near the site of the Indian church, now occupied by a Unitarian church.
