Carpenterstown (townland, Castleknock)

[3] In geology, the townland rests on a substratum of limestone and comprises 166 statute acres, the whole of which is arable land.

The land occupied by the "Carpenter" pub and by Castleknock Community College is actually in the latter townland, not in Carpenterstown proper.

[5][6] The five landowners were: Many large houses occupied both sides of the Carpenterstown road where it forms the southern boundary of the townland.

[citation needed] The Royal Canal crosses the top end of the townland from west to east between the 13th and 12th locks.

Anomalously, the church building itself is just outside the townland proper as it is to the east of the treeline that separates Carpenterstown from Blanchardstown.
