 It is also described as having a slim circular projection on the south-east corner with slit windows, rising higher than the tower, and also having an embattled parapet.The Irish Tourist Association survey of 1944 states that it was erected 100 to 120 years previously, cost £100, and was built by Commodore Crooke of the British Navy.The survey holds that 'Crook's Tower' would be a more accurate description, and that it consisted of two narrow sections with the cylindrical portion slightly higher than the rectangular element.
