Barmeath is situated near Dunleer in the centre of the county and looks out across Dundalk Bay towards the Cooley peninsula. The house was originally an outer castle of the Pale and is of great heritage interest due to its multi-layered architectural history and the survival of outstanding gardens by the 18th century landscape architect Thomas Wright.

The Irish Georgian Society has grant aided essential works to repair a conical roof on one of the corner towers of the castle and uses these works to demonstrate best conservation practice. In repairing the roof the Society has ensured the protection of a gothic vaulted ceiling within a garden room at ground floor level. The conservation architect for these works was James A. O’Connor & Assoc. and the builder was William McQuillan.
