(Kings of Connacht). The site is on private property and is not open to public access. The hill is above sea level and so visible from many places in the surrounding area. The best view of the site is from the Old Kilcullen churchyard in Old Kilcullen (where there is also a round tower), which is free and open to the public. Dún Ailinne should not be confused with the Hill of Allen (Cnoc Alúine), which is to the northwest.

History and purpose

The site is circular, about 13 ha (32 ac) in area, ringed by an earth bank and ditch (or "

"). As with most henges, the ditch is on the inside, meaning that it was likely to have been symbolic rather than defensive. It is believed that Dún Ailinne was a royal centre and inaugural or ceremonial site for the Kings of Leinster. In terms of its ritual use, the internal structures and layout, and its location and association, is similar to the other royal sites of Tara, Navan Fort and Rathcroghan (Johnston 2006). Indications of earliest use are from the

e have also been found at the site (Johnston and Wailes 2007). While it figures in some early historical references, Dún Ailinne was mostly abandoned about the time the nearby early Christian settlement at Old Kilcullen was established in the 6th century.

Structures

Excavations during the 1960s and '70s found that there were once timber structures within the ring. There were three phases of construction, each including rings of upright timber posts. One of these, the Rose phase, had a figure of eight layout, with one large ring, an annexe to the south, and an elaborate funnel-shaped entrance. The later Mauve phase had a stakewall, within which were a timber ring and smaller, closed, circular structure. The last phase was characterized by ceremonial feasting, indicated by a large amount of animal bone (Johnston and Wailes 2007).

led by Bernard Wailes. More recently, a geophysical survey of the interior was carried out by a joint American and Irish team (Johnston, Campana, and Crabtree 2009). This revealed a large number of new subsurface features whose character is unclear. Following some scholarly journal publications, a book was released by an American university publisher in 2007, by Bernard Wailes and Susan Johnston. In 2008, an interpretative site was opened at Nicholastown, a townland just south of Kilcullen, featuring a bilingual information panel (Irish and English) and a small-scale reproduction of the mound, topped by a sculpture.

Current status and access

The whole site is on private farmland and casual access is restricted due to difficulties with livestock; if there are cattle on the hill then access is not possible. If they are not there, however, you can ask the landowner and you may be given permission to have a stroll around the site.
