"Knole House, near Sevenoaks, is perhaps the largest
of the Kentish mansions. The earliest parts were built
in the fifteenth century, but the main portion is chiefly
Elizabethan. It is a quadrangular house, with embattled
gateways and square towers, and is most beautifully
situated in an extensive park, which has deep hollows
and a splendid variety of trees."
