Why this matters
Cloghadalton (Castlelloyd) was likely a small medieval stronghold, possibly built by a local Gaelic family in the early modern period. It is remembered primarily through early 20th-century archaeological notes, though its exact historical significance remains unclear due to limited surviving records.
