- RO027-028001 House - 17th century
Description
Marked as a small rectangular building and described as a 'Castle' in gothic lettering on the 1837 ed. of the OS 6-inch map, it is situated at the summit of a broad hill. Regarded locally as the site of a castle of the Plunkett family who were transplanted here from Meath in the mid-17th century. They lost their lands in the early 18th century to landowners called Knox, who never occupied it. The castle was used as a fever house during cholera outbreaks (1825-1835) and it was burnt before 1840. It is not visible at ground level in pasture.
