The remains of an 18th century streetscape have been uncovered at Dublin's Iveagh Market, Francis Street, which is being redeveloped as a multi-purpose market with adjoining hotel.
Preliminary excavation of the site has revealed three phases of foundations, from the 1700s or later, including the remains of a brewery. The findings - about eight feet under current street level - correspond closely with old maps of the city, including the Roque map which features on the £10 note.
There are no medieval remains in the find, according to consultant archaeologist Ms Margaret Gowen. "There's a good reason for that because this is the site of the old fair green where animals were bought and sold. So we were unlikely to find medieval architecture."
A report on the exploratory stage of the excavation will be sent to Duchas, the Heritage Service, within days for a decision on whether the material should be preserved on site or recorded and removed.
The former option would have major implications for the development plans which include an extensive basement area. The archaeological study is being funded by the developer, Mr Martin Keane.
