The Martyr's Memorial, a Gothic structure like a church spire, erected in 1851 to commemorate Christopher Waid who was burnt at the stake during the reign of Queen Mary. Richard Trevithick (d. 1833), the Cornish engineer and pioneer of steam locomotion, is buried somewhere in the former churchyard of St Edmunds. The graveyard was turned into parkland in the 1960s and the exact location of his grave now is unknown. Burials in the graveyard stopped around 1857.
