The Essential
Ferns was the main religious centre of the province of Leinster in the early centuries of the Middle Ages, with St Mary's Abbey; built in the early 12C, it burnt down in 1154 and was later rebuilt. All that remains of the church is its tower and a few sections of wall. The 13C castle has retained its walls and moat, as well as its keep with crenellations and arrow-slits, which offers a panoramic view over Ferns and the surrounding area.
