[1][2][3] Drumlohan souterrain and ogham stones are located in farmland 4 km (2½ mi) east of Lemybrien.

[5] The souterrain is believed to have been constructed around the 9th century AD and is aligned WSW, facing the setting sun.

Souterrains were storage sites and places of refuge.

[6][7] In July/August 1867 a local farmer rediscovered the souterrain and ogham stones.

In 1936 part of the souterrain was dismantled and some of the ogham stones re-erected above ground.
