Rosbercon Abbey was a Dominican Abbey at Rosbercon, County Kilkenny. Founded in 1267, it was suppressed in 1539. A fragment survived as late as the1820s, but little trace remains now.
The founders were two prominent local families, the Walshes and Graces. It never seems to have been a house of any importance, and little more is recorded until 1539, when Matthew Fleming, the last abbott, surrendered it to Henry VIII. [1]The KIng granted it to John Parker (Irish judge) the Master of the Rolls. [2]It is unclear whether Parker, who lived near Dublin, intended to convert it into a house, but in the event it seems to have been left to decay. A sketch from 1823 shows a small ruin with New Ross in the background.
