Dún Naas

Naas (Irish: Nás na Ríogh, or An Nás) is the county town of County Kildare, Ireland (Irish: Contae Chill Dara, Éire). In the town is Dún Naas or Mote of Naas was a fortification associated with Luighdech Eithlenn, King of Leinster. It was built in 140 AD on the location of a previous fortification and was itself subsequently destroyed and rebuilt by Princess Tailtinn. It is situated on Abbey Road beside the Moat Club. The site now consists of two north and south earthwork motes (earthwork mounds) the largest one remaining at the north. The North Mote is about ten metres high and has a diameter of almost one hundred metres at the base. It is thought, that what can now be seen could have been built in Viking or early Norman times, but is on the site of the Dun of the Kings of Leinster. The South Mote, which can be found on the site of the present Fairgreen, is now only detectable as a low hillock. 

Lnks: There is interesting short history about this site on the website of the The County Kildare Federation of Local History Groups. It is also worth reading an article by Paddy Behan, Naas Local History Group, 1999. Here is the link and the title is Looking back on Naas Moat history.  The image is taken courtesy of that article.
