Dún Ailinne, Iron Age hillfort in County Kildare, Ireland
The circular enclosure spans 13 hectares on Knockaulin Hill, featuring an earth bank and internal ditch measuring 500 by 400 meters across.
Archaeological excavations revealed three distinct phases of timber structures between 400 BCE and 400 CE, indicating the site's evolution through the Iron Age period.
The site served as a ceremonial center for the Kings of Leinster, comparable to other royal locations like Tara, Navan Fort, and Rathcroghan.
Access to Dún Ailinne requires permission from landowners as the archaeological site sits on private farmland with active livestock grazing.
Saint John's Well, the sole water source on the hill, remains on the north side of the site with reported healing properties for rheumatism.
