A Type-23 Pillbox stands at the gate to Scarvagh House in Scarva, Co. Down. It overlooks the Second World War era stop-line B on the Newry Canal and River Bann.
The Scarvagh House Pillbox on the outskirts of the Co. Down village formed part of defensive stop-line B, which ran from Lough Neagh to Carlingford Lough. The line followed the route of the River Bann and the Newry Canal. The stop lines east of the River Bann in Northern Ireland were constructed in 1940.
Inside the pillbox remains a platform where, after 1941, Turnbull Mounts would have held a pair of guns – either a Vickers Machine Gun or a Bren. Parts of the Turnbull Mount frame and ammunition recesses are still visible inside the pillbox. Entry to the pillbox was through a doorway in the rear, which once would have benefitted from the protection of a concrete blast wall.
