What is "rosnaree"

Rossnaree ( Old Irish Ros na Ríg) is a small village in County Meath, Ireland, on the south bank of the River Boyne, near the Brú na Bóinne complex of neolithic monuments on the north bank. It commands a ford that was used by the Williamites at the Battle of the Boyne in 1690. The walls of the mill at Rosnaree once contained a Sheela na Gig, although this has now been removed for safe keeping.
