It measures roughly three metres north to south and just over two metres east to west, with what may have been an entrance facing east. The interior is now filled with rubble. What makes it worth a second glance is its name, Clochán an Airgid, which translates roughly as the stone hut of money or silver, a name that tends to attach itself to places carrying some faint legend of buried wealth or unusual significance.

A clochan is a type of dry-stone corbelled structure, built without mortar by laying stones in gradually narrowing rings until they meet at the top, a technique with deep roots in early medieval Irish monastic and rural life. This particular example, in the townland of Eochaill on the Aran Islands, shares its local name with another clochan in the nearby townland of Eoghanacht, which is a curious doubling. Whether the shared name reflects a common tradition, a forgotten story that attached itself to both structures, or simply a local habit of naming such features similarly, is not recorded. Tim Robinson documented the name in 1980, and it appears in Paul Gosling's Archaeological Inventory of County Galway, published in 1993.
