Donnelly's Hollow is a small hollow on the Curragh, but it carries one of Kildare's stranger local stories. It is linked with Dan Donnelly, the celebrated bare-knuckle boxer whose early 19th-century fights became part of Irish sporting folklore, and the hollow keeps that rough social history tied to the open grassland.
This is not a polished attraction; the appeal is in the setting and the story. It is worth adding to a Curragh drive or walk if you are interested in horse country, old sporting culture, or the less tidy corners of Irish history. Read up before you go, because the ground itself is understated.
