Drimnagh is a suburb of Dublin, Ireland, situated on the Southside of the county between Walkinstown, Crumlin and Inchicore, bordering the Grand Canal to the north & east. Drimnagh Castle was, until 1954 one of the oldest continually inhabited Castles in Ireland, and is an outstanding example of an old feudal stronghold. It is the only Irish castle still to be surrounded by a flooded moat, a very picturesque feature, described in 1780 as a “very deep ditch of water supplied from the Green Hills”. It is now stocked with fish. The castle, built of local grey limestone, consists of a restored Great Hall and medieval undercroft, a tall battlement tower with lookout posts, and other separate buildings including stables, old coach, dairy and folly tower. One of the most attractive aspects of Drimnagh is the garden – a formal 17th Century layout with box hedges, yews, mop head laurels and an allee of hornbeam.
