The rath at Kilcolman in north Kerry has three. Three gaps cut into the enclosing earthen bank, one each in the north, south, and east sectors, which is unusual enough to make you wonder what kind of place this was and who came and went through it.

A univallate rath, meaning one enclosed by a single bank and ditch rather than multiple concentric rings, was the standard form of rural settlement in early medieval Ireland, typically associated with a farming family of some local standing. This one sits on gently sloping ground with wide views in every direction, a practical advantage for anyone keeping watch over livestock or land. The internal diameter measures 28 metres, a reasonably substantial enclosure. The bank itself rises to two metres on the outside face and 1.6 metres on the interior, enough to mark a clear boundary and provide a degree of shelter and security. The three entrance gaps measure three, three, and four metres across respectively, all of them modest openings, but their number and placement across different compass points gives the site an open, almost welcoming quality at odds with the usual logic of enclosure. Whether the gaps represent original design, later modifications, or simple deterioration over centuries is not recorded.
