This circular rath on a north-facing slope in Carrowpadeen, County Galway, carries a local name that sets it apart from the thousands of similar enclosures scattered across Ireland: it is known as the Fort of the Three Shouts, a designation recorded as far back as 1914 by Neary. Whatever the shouts referred to, whether a ritual, a warning system, or something absorbed from older legend, the name has clung to the place while its original meaning has dissolved.

The earthwork itself is a bivallate rath, meaning it is enclosed not by a single bank and ditch but by two banks with two intervening fosses, or ditches, giving it a more substantial defensive or symbolic presence than simpler single-banked examples. At forty metres in diameter, it falls within the typical range for Irish ringforts, the broad class of enclosed farmsteads built predominantly during the early medieval period, roughly between the fifth and twelfth centuries. An inner scarp adds further definition to the interior. The entrance faces north, which is comparatively unusual, most ringfort entrances tending to face east or south. Quarrying has done some damage at the southern and north-western sides, eating into the enclosing banks and fosses, and a later field bank has been laid across the outermost bank at the north-north-west. Despite these intrusions, the structure is described as well-preserved. A second ringfort sits approximately four hundred metres to the north-west, suggesting this part of Carrowpadeen supported more than one enclosed settlement in the early medieval period.
