The buildings surround two courtyards paved with large stones, and cover a space of nearly three hundred feet square. Outside the arched entrance-gate to the first courtyard is a low thatched cottage used as a porter's lodge. Haddon is maintained, not as a residence, but to give as perfect an idea as possible of a baronial hall of the Middle Ages. To get to the entrance the visitor toils up a rather steep hill, and on the way passes two remarkable yew trees, cut to represent the crests of the two families whose union by a romantic marriage is one of the traditions of this famous place. One yew represents the peacock of Manners, the present ducal house of Rutland, and the other the boar's head of Vernon.
Parts of this house, like so many structures in the neighborhood, were built in the time of "Peveril of the Peak," and its great hall was the "Martindale Hall" of Scott's novel, thus coming down to us through eight centuries, and nearly all the buildings are at least four hundred years old.
