The structure appears on the Ordnance Survey Fair Plan positioned immediately southwest of the castle, suggesting a clear defensive relationship between the two structures that was common in Irish castle design from the medieval period onwards.

By 1837, when the Ordnance Survey mapped the area at six inches to the mile, the bawn had already deteriorated into little more than a rectangular field boundary measuring approximately 37 metres from northeast to southwest and 34 metres from northwest to southeast. These dimensions suggest a modest but practical defensive space, typical of the smaller tower house bawns found throughout the Irish midlands.

Today, visitors to the site will find little visible evidence of this once vital defensive structure. The grass has reclaimed most of the area, leaving only the faint outline of wall footings visible to the trained eye. These subtle traces in the landscape serve as quiet reminders of a time when such fortifications were essential for survival in rural Ireland, protecting both people and cattle from raiders and rival clans. The archaeological record, compiled by Olive Alcock in October 2012, preserves the memory of this forgotten piece of Longford’s defensive heritage.
