The origins of the park lie in the lands surrounding a house named Belcamp Park in the 17th century. The then Lord Mayor of Dublin, Sir
Humphrey Jervis, built a house on a property in what was then a rural area, probably in the 1680s, though he never lived there, dying in debtors prison in 1707. The estate was then sold to the Grattan family, and local tradition holds that
Henry Grattan was born there in 1746.
Jonathan Swift was acquainted with the Grattans, and their cousins the Jacksons at the nearby Woodlands estate in
Clonshaugh, and is known to have visited at least a dozen times between 1714 and 1734.
Laetitia Pilkington also stayed at the house in 1730 and later documented anecdotes of this visit concerning Swift in her
Memoirs. The Grattan ownership of the estate ended in 1770 and it passed through many hands over the following centuries.
Countess Markievicz rented the property in 1909, to utilise it as a centre for the
Fianna Eireann. The estate was bought in 1969 by
Dublin Corporation. Belcamp Park house was damaged by fire in 1977 and subsequently demolished, leaving behind some outbuildings and an
ice house. ==Belcamp Hall and Belcamp==
