There are three graveyards in the parish of Garristown, one in Ballymadun one in Rollestown and one in Garristown all in the Co. Dublin.
In the centre of Garristown graveyard there are the ruins of an old Protestant church. The graveyard is square and is surrounded by a wall. A number of palm trees grow in the graveyard. Formerly there were five or six beech trees in it. About three years ago the parishioners decided to have them cut down. There is a number of fine headstones in the graveyard most of which are made of stone or marble.
