About Finnstown

A large residential neighbourhood in the Lucan area, Finnstown grew from the grounds of the former Finnstown House — now a hotel and golf course — into one of west Dublin's most established suburbs. The housing estates that developed from the 1970s onwards are mature and well-maintained, with schools, parks, and a strong sense of community. The proximity to the N4 and Liffey Valley keeps the area well connected to both the city and the western commuter belt.
