Knock Abbey is an amalgamation of two fascinating structures - a medieval tower keep and an elegant Georgian house with added Victorian embellishments. Recently renovated, it was originally owned by the Tennison family and for more than two hundred years was the home of the O'Brien family. Now open to the public for its fine restored gardens, it is full of fascination and the texture of centuries.
