CAPNI Excavations
The excavation at Erenagh sought to uncover evidence for the now-lost medieval monastery. The Cistercian abbey was founded in 1127 by Niall Mac Dunlevi, king of Ulster; however, it was destroyed 1177 by John de Courcy (who later rebuilt Inch Abbey to make amends). Historical evidence suggests a church remained on the site for centuries, but today there are no standing remains visible. A geophysics survey showed evidence below the surface of what could be an extensive building complex. The excavations revealed a number of walls and metalled surfaces, suggesting buildings and occupation. A medieval date for the buildings is supported by the find of a Long Cross Penny of Edward I.
Today Moira Demesne is a public park, opposite the church. But in the mid-1600s, Major Edward Burgh constructed a 'fine brick house' on the site; this was later acquired by Sir George Rawdon and remained in his family for generations. The excavations sought to expand on work carried out by the CCA in 2018 and 2019, which uncovered remains of a building, a stable yard and Bronze Age features. The 2025 excavations uncovered a cobbled surface and a large building, possibly a glasshouse or other outbuilding. One of the many finds included a fragment of a wine bottle embossed with the crest of the Rawdon family.
