PEVENSEY, (Sussex) or PEMSEY, which gives name to one of its rapes, lies to the N. E. of Beachy-Head. It had a noble castle built by William the Conq. who, some say, first landed here. It was given by Hen. IV. to the ancient and noble family of the Pelhams, who enjoy it to this day. It was anciently a famous haven; but is now accessible only by small boats, that crowd up a little rill to it.
