RICHBOROUGH, (Kent) near Sandwich, and about 1 m. from the sea, was in the Romans time, before its port was choaked up by the sands, a famous harbour, where their forces used to arrive from Italy, and where they built a castle; and it was also the common landing-place from France. It flourished under the Saxons by the name of a city; and had a palace of Ethelbert, the first K. of Kent, who used to confer here with St. Augustin, then residing at Stoner. The Danes destroyed both the city and castle; but in some places the old walls of the tower are visible, and a noble remnant of Roman antiquity. Roman coins, both gold and silver, are often ploughed up here. The r. Stour from Canterbury runs under the cliff by the castle, and so by Sandwich.
