Milltown Castle, County Louth is thought to date from the early 15th century when built for the Anglo-Norman Gernon family, who long held land in this part of the country. In many respects it is a typical tower house of the period, but made unusual by having rounded corners and a couple of semi-circular towers. Of four storeys, it underwent the usual alterations across the centuries but remained in use as a residence until relatively recently; a 19th century photograph shows buildings attached on either side, including a two-storey house, but these have since been demolished and today it stands in a farm yard (guarded by a pair of rather aggressive dogs, hence no closer pictures…)
