According to the Civil Survey of 1654-6, this was the Manor Court and lands of “Archybald Lord Archbishopp of Cashell” in 1640, complete with a large stone house surrounded by a protective bawn. The castle likely served as the country residence for the Archbishops of Cashel, with records noting that Archbishop Malcolm Hamilton died here on 25th April 1629.

The ruins reveal the impressive scale of the original complex. A roughly oval area measuring approximately 50 metres east-northeast to west-southwest and 40 metres north-northwest to south-southeast is defined by the remains of a levelled scarp, varying in width from 8 to 22 metres. Two mural towers once stood as part of the fortifications; one still abuts the northwest section, whilst another to the southeast, marked as “Camus Castle (in Ruins)” on 6-inch Ordnance Survey maps, is no longer visible at ground level. Writing in 1892, White noted that remnants of the bawn could be found in four different locations, with the principal section standing directly over the River Suir and what was probably a gatehouse positioned to the south, suggesting the castle enclosed a considerable courtyard.

Today, the most prominent survivor is a rectangular mural tower built into the southeast bank of the River Suir. Measuring 3.85 by 10.15 metres, only its northwest and southwest faces remain, constructed from roughly cut and coursed limestone blocks with a base batter reaching 2.25 metres in height on the northwest side. The southern end of the southwest face stands 3.1 metres above ground level, though time has taken its toll; the quoins at the southern angle have been broken away, whilst those at the northern angle, though roughly dressed, are missing their lower stones. Patches of external render still cling to the northwest face, offering glimpses of how this formidable structure once appeared when it guarded the Archbishop’s manor.
