Luttrellstown Castle is a castellated house located in Clonsilla on the outskirts of Dublin, Ireland dating from the early 15th century (c. 1420).

The stream exits the south-eastern corner of the demesne at a gate lodge on the Strawberry Beds, passing under the road before falling into the River Liffey 25m later.

He was suspected of betraying the Irish leader Patrick Sarsfield, either by his precipitate withdrawal of his Jacobite troops or by giving the army of King William III of England strategic information about a ford of a river, leading to the loss of the Battle of Aughrim in 1691.

For this act, he was rewarded with the forfeited estates of his elder brother, Simon Luttrell, including Luttrellstown, and was made a major general in the Dutch army.

He served as a Member of Parliament for Bossiney in 1768, and subsequently was Adjutant General of Ireland, where he became notorious for his role in suppressing the Irish Rebellion of 1798.

He was so hated that he sold Luttrellstown Castle in 1800, but in a revenge attack, the grave of his grandfather Colonel Henry Luttrell (died 1717) was opened and the skull smashed.

[11] Luttrell was an absentee landlord who also owned an estate in the West Indies but resided at Painshill Park in Surrey, England.

Due to this, he later had the Royal Marriages Act 1772 passed to prevent any descendant of George II marrying without the consent of the sovereign, a law which remained in effect until the passage of the Succession to the Crown Act 2013, which, in addition to several other modifications, limited the requirement to obtain royal consent to only the first six persons in line to the throne (rather than all descendants).

Henry Lawes Luttrell sold Luttrellstown to publisher Luke White in 1811,[12] described as one of the most remarkable men that Ireland produced and ancestor of Lord Annaly.

In 1900, en route to the Viceregal Lodge she drank a cup of tea near the waterfall, an event commemorated by Lord Annaly with an obelisk made of six granite blocks from the Dublin mountains.

In 2007, more than €20 million was spent on major upgrade work, including improvements to the Steel and Mackenzie designed championship golf course and the "alpine style" clubhouse.
