Donaghmore Souterrain is a souterrain and National Monument located in County Louth, Ireland.
Donaghmore Souterrain is located 3.6 km (2.2 mi) west of Dundalk, near a cluster of houses.
Souterrains are cave-like structures built as places of refuge and storage, and in Ireland they date between the 8th and 12th centuries.
The souterrain was discovered in 1960 during the construction of a Louth County Council cottage. It was excavated by Etienne Rynne who found trenches, a pit, two post-holes, sherds of souterrain ware, a bronze pin, a whetstone and iron slag.[citation needed]
The souterrain at Donaghmore is a complex of tunnels lined with dry stone walls, floors and ceilings, with corbels and lintels. The ceilings are over 1 m (3 ft 3 in) in height and the total length of tunnel is 80 m (260 ft). It is largely dug into boulder clay but also into Silurian grit.
