Though the castle and its associated bawn have long since vanished from view at ground level, their story remains etched in historical records. Pierce Butler held these lands as proprietor in 1640, when the castle still commanded impressive views across the surrounding countryside in all directions.

The castle formed part of a larger defensive complex that included a bawn, or fortified courtyard, positioned to its west. Modern farm buildings now occupy the spot where this protective enclosure once stood, effectively erasing its physical presence from the landscape. The Ordnance Survey Letters noted that remnants of the bawn's outer walls were still visible in the 19th century, though observers remarked they appeared to be of more recent construction than the castle itself, suggesting the site underwent modifications across different periods.

Today, visitors to Fennor will find little evidence of the castle's former glory, but the site retains its historical significance within the local landscape. Just 130 metres to the southwest, a church and graveyard dating from the same era continue to serve as tangible reminders of the area's medieval past. The elevated position that once gave the castle its strategic advantage now offers modern visitors the same sweeping vistas that Pierce Butler would have surveyed from his stronghold nearly four centuries ago.
