ABBOTSTOWN HOUSE, Castleknock, County Dublin, is a two-storey house, extended at various times, though mainly early to mid-19th century. 
 
It has a five-bay entrance front, the central bay breaking forward with a triple window above a projecting, pilastered porch. 

 
There is a similar side elevation, with a single-storey, pillared bow in lieu of a porch; elongated by a full-height curved bow. 
 
Abbotstown House remained the seat of the HolmPatricks until 1947, when the 3rd Baron lost part of his lands under a Compulsory Purchase Order to allow for the building of a Hospital. 
 
Later, Lord HolmPatrick sold remaining lands at Abbotstown to the Marine Institute of Ireland, which was located at Abbotstown House until 2005, when the house was acquired for Sports Campus Ireland. 
 
In the late 1990s, half of the lands under the ownership of the local health board were sold for development in order to finance the redevelopment of the hospital buildings.
