Place & story
A residence and its orchard
A fortified house in Newcastle appears in the historical records associated with the Roche family. The Civil Survey recorded Jordan Roche’s holding here in 1640 as including a castle and fifteen acres of orchard. The surviving ruin therefore represents a residence within a managed estate landscape, rather than a military structure standing entirely apart from domestic and agricultural life. [2]
The ruin described in 1840
An Ordnance Survey account from 1840 described Newcastle’s castle standing on rock, with openings for five floors and walls rising about fifty feet. Its west wall was already gone. Local informants said a corner tower had fallen with that wall around forty years earlier. These observations, reproduced in the archaeological assessment, document substantial damage long before the present-day ruin. [2]
Burnt material beneath the ground
Tracy Collins’s 2002 testing in Newcastle, Castletroy, examined a mound that proved to be natural. One trench nevertheless exposed burnt stony material and two circular pits containing similar deposits. The features were interpreted as a possible fulacht fiadh, with the pits perhaps serving as troughs. The discovery adds evidence of prehistoric activity without turning the initially suspected mound into a constructed monument. [3]
