This earthen embankment, measuring 4.5 metres in diameter, stands just 30 centimetres high and spreads 1.5 metres wide. What remains today appears to be only the southwestern half of what was once a full circular enclosure, now weathered by centuries of Atlantic winds and grazing livestock.

The site occupies a strategic position in an area of relatively good pasture, with sweeping views westward across Teelin Bay. Such locations were often deliberately chosen by early inhabitants, offering both practical advantages for keeping watch over the surrounding countryside and access to coastal resources. The modest height of the bank suggests this wasn't a defensive structure, but rather a domestic site; possibly the foundation of an ancient roundhouse or a small enclosed settlement typical of Ireland's prehistoric and early historic periods.

This archaeological feature was documented as part of the comprehensive Archaeological Survey of County Donegal, conducted by Brian Lacey and his team in 1983. The survey catalogued field antiquities spanning from the Mesolithic period through to the 17th century, creating an invaluable record of the county's rich archaeological heritage. Though the Doire Leathan hut site may appear unremarkable at first glance, it represents one small piece in the vast puzzle of human occupation along Ireland's Atlantic coast, where generations of people made their homes long before written history began.
