Though you won’t see any stones or walls today, this spot once housed a castle and its protective bawn, structures that stood here for centuries before vanishing completely from view. The site appears on the first edition Ordnance Survey map from 1840, marked simply as ‘Castle’, whilst the 1904-05 edition more cautiously labels it ‘Castle (site of)’, suggesting even then that physical traces were becoming scarce.

The Civil Survey of 1654-56, one of Ireland’s most important historical documents, provides a tantalising glimpse of what once stood here. It describes ‘an old castle within an old Bawne’, indicating that by the mid-17th century, both structures were already considered ancient. A bawn was essentially a fortified courtyard wall that surrounded and protected tower houses and castles in medieval and early modern Ireland; these defensive enclosures were particularly common during the plantation period when security was a primary concern for landowners.

Today, the site at Frehans offers no visible remains at ground level, making it one of countless lost castles scattered across the Irish countryside. These vanished fortifications remind us how much of Ireland’s built heritage has been reclaimed by the land, leaving only historical records and old maps to mark where communities once gathered, defended their territories, and shaped the landscape we see today.
