Fitzwilliam period

The earliest mention of a castle here is in a deed of 1334.
Merrion came into possession of a branch of the Fitzwilliam family in early 1400s.
It came into the possession of Thomas Fitzwilliam in late 1400s. He died 1517.
His son Richard Fitzwilliam leased out Merrion in 1519 when going to England for a time. He died 1528.
Merrion was made the seat of the family by his son Sir Thomas Fitzwilliam around 1550.
The Lord Deputy Sir Henry Sidney visited Sir Thomas at Merrion in 1565 after arriving in Ireland and before entering Dublin.
Sir Thomas died 1592.
His son Sir Richard Fitzwilliam died at Merrion in 1595.

His son, the future 1st Viscount Fitzwilliam, succeeded to Merrion in 1595.
See Merrion Castle in the "riding of the bounds" of Dublin in 1603.
The castle was damaged in the Irish Confederate Wars (1641 to 1653). It was overrun by the rebels in 1642. It was later taken and garrisoned by the Parliamentarians as at 1648. It was afterwards restored.
The 1st Viscount died c.1655.
The 2nd Viscount Fitzwilliam (1st Earl of Tyrconnel) died at Merrion Castle in 1667.
The 4th Viscount Fitzwilliam spent time living in England, and Merrion Castle fell into disrepair.
The 4th Viscount died 1704.

The castle was abandoned by the 5th Viscount Fitzwilliam in 1710.
Merrion Castle had sunk into decay by 1729.
This was reported in Walsh's Impartial News Letter, Dublin, 16 May 1729, which is a continuation of the Dublin Mercury. Can't find surviving copy.
This was reported in the Flying Post, Dublin, 16 May 1729. Can't find surviving copy.
The ruins of Merrion Castle were described by Austin Cooper in 1780, and were being removed in 1780-1781. But a ruin survived for many years.

The new "Merrion Castle"

A new building called "Merrion Castle" was built at the site in the 18th Century. This survives today at the far left (S end) of the new buildings.
[Pettigrew & Oulton, 1834] shows "Merrion Castle" (would be the new building) is then occupied by "Lady Harberton".
MERRION in [Lewis, 1837] lists "Francis Low" at the new Merrion Castle, and says the ruin of the old medieval castle is in the grounds: "In the demesne of Merrion Castle are the ivied ruins of the old castle from which it derives its name".
[Pettigrew & Oulton, 1838] shows Merrion Castle occupied by "Francis Lowe".
The entry for "Old Merrion" under MERRION in [Thom's, 1852] shows Francis Low at the new Merrion Castle, "in the grounds of which .. are the ivied ruins of the castle of the ancient proprietors."

St.Mary's school for the blind

The Sisters of Charity set up a home and school for the blind at Merrion Castle, starting in 1865.
Page 470 in [Blacker, 1860-74] says that the new "Merrion Castle" became St.Mary's Asylum for the Female Blind in 1865 and "additions on an extensive scale" were then made to the building.
[Smyth, 1994] says the ruin of the old medieval castle was only fully removed around 1866.
[Wilkinson, 1925] says: "No vestige remains of the old castle, but some of the stone may have been used in building the Asylum for Female Blind which now occupies the site".

The site became St.Mary's Centre, school for the blind and nursing home.
It had an area of residences called "Fitzwilliam".
It closed in 2020.
The site awaits redevelopment.

A medieval stone plaque, bearing the Fitzwilliam coat of arms, survives at the site. A medieval stone head also survives.
A bit to the SE (along the coast road) is Merrion graveyard.

Elm Park Stream

Elm Park Stream ran through the grounds of Merrion Castle.
It is perhaps as close as we can get to re-imagining the old Merrion Castle.
The stream still runs through Elm Park golf club, through the grounds of St.Mary's, then it is diverted underneath the Merrion Road, and discharges into the sea on the strand.
See [Sweeney, 1991].
