On the corner of Parliament St and the road leading down to Bateman's Quay, this monument (really just a fragment) built into the Bank of Ireland marks the site where the national Parliament met from 1642 to 1649. Nearby is the carefully restored Grace's Castle , originally built in 1210, but lost to the family and converted into a prison in 1568, and then in 1794 into a courthouse, which it remains today. Rebels from the 1798 Rising were executed here.
