That kind of built-in timestamp is unusual enough to catch the attention, and here it anchors the tower firmly to the era of pre-Famine rural industry, when windmills were still a working part of the Irish agricultural landscape before steam and later electricity made them obsolete.

The tower is conical in form, built across three floors, with an external base diameter of 7.6 metres and an internal diameter of 5.9 metres. Two doorways face each other on the east and west sides, a practical arrangement that would have allowed the miller to enter or exit regardless of which direction the wind was blowing equipment or grain. Two windows appear at each floor level, providing both light and ventilation within what would have been a working interior. The structure survives to its near-full height in reasonably complete condition, which is notable given how many Irish windmill towers of the same period have lost their upper sections or collapsed entirely. Ordnance Survey maps from 1839 and again from 1925 both mark the site plainly as a windmill, confirming it was recognised and functioning, or at least standing, across nearly a century of cartographic record. The townland name, Chapel, gives little away about the tower itself, though the flat terrain surrounding it would have made it well-suited to catching prevailing winds without obstruction from hills or woodland.
