The monument consists of anti-invasion defences, dating to the early period of World War II (AD 1940-41), that formed part of Western Command's Carmarthen Stop Line, which ran N from the mouth of the Afon Tywi to Carmarthen, thence to Cynwyl Elfed, Rhos, Henllan, Llangeler via Rhydlewis to Llangranog. The line formed part of the defences for anticipated operations against Milford Haven, Port Talbot and Swansea. The pillboxes are located on the south side of Cynwyl Elfed. Item A is a standard Type 24 pillbox, which faces southwest covering the Nant Ring valley. Item B is a Norcon type pillbox located at the junction of an old drove road with the A484 trunk road. Item C is a Norcon type pillbox located in the Nant Ring valley. Item D is a standard Type 24 pillbox and faces southwest across the Afon Duad valley.
The monument is of national importance for its potential to enhance our knowledge of World War II anti-invasion practices. The monument is well preserved and is an important relic of actions taken against the perceived threat of a German invasion from Ireland. The two Norcon pillboxes are the only known examples to survive inland in Wales. The monument retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The importance of the monument is enhanced further by its group value with the anti-invasion defences at Ty Cwm Tawel located 2Km to the southeast (scheduled ancient monument CM372).
