The castle sits on 250 acres (101 hectares) - though much of it is given over to dull-looking playing fields - and the perimeter is just over three kilometres (two miles) long; a good distance for a walk, and largely sheltered by mature trees. Historic home of the de Talbots, the castle itself is an interesting hotchpotch of architectural styles: Norman and Gothic features co-exist with beautiful period furniture.
There's an extensive collection of Irish portrait paintings, and faces from history stare down at every turn (some are on loan from the National Portrait collection, others are the family's own). One in particular - Van Wyck's commemoration of the Battle of the Boyne in 1690 - is poignant, showing the 14 family members who sat down to breakfast the morning of the battle before joining King James to fight William of Orange. Not one returned. In the basement is a dimly lit self-service café that serves really good, fresh, own-made food. There's also a model railway (open in the summer months only, except on Wednesdays), and outside is an excellent adventure playground.
