The graveyard of St Mary's Church in Richmond contains a Plague Stone. The Stone marks the pit where 1,072 people where buried, having been overcome by the Black Plague between 1597 and 1599.

The Plague Stone is unmarked, containing no etching and no wording, and is simply blank. The Bell Tower of the church faces west, and the apse faces east. The location of the Plague Stone is quite close to the north face of the church near to the apse, and is conspicuous because of its blank sides.

Richmond has a second Plague Stone, located further to the south east of the church, nearer to Mercury bridge and the north east bank of the River Swale. The second stone marks the Plague Pit where another 700 people were buried during the further outbreak of the Black Plague between 1644 and 1645. The second Stone is midway between the Church and the Clink Pool.

Further outbreaks of the Black Death are not likely to occur, man having discovered its cause and having created a vaccine to prevent it.
