The earliest recorded mention dates to 1336, when the site at Ballynaclochy formed part of the Cluaincheur manor under Bishop de Rupefort’s control. By 1583, the castle had passed to E. oge Lacy of Knockpatrick, though it was already showing signs of decay; contemporary records describe it as “broken and ruinous”, accompanied only by a waste croft or garden. The property changed hands again in 1587 when it was granted to F. Trenchard, and by 1655, Nicholas Lylles had taken possession.

The Civil Survey conducted between 1654 and 1656 provides a snapshot of the property during the Cromwellian period, confirming that Nicholas Lylles, described as an English Proprietor from Limerick, held both a castle and an orchard at the site. This period marked a significant transition in Irish land ownership, with many properties transferring from Irish Catholic to English Protestant hands following the Confederate Wars.

By the 19th century, the medieval castle had given way to Ballyclogh House, a three storey rectangular residence that became home to the Copely family. Writing in 1840, surveyors noted that John Copely had undertaken repairs to the house in 1810, ensuring it remained in good condition. This transformation from medieval fortress to Georgian country house reflects a broader pattern across Ireland, where ancient defensive structures were replaced by more comfortable domestic dwellings as the country became more politically stable.
