STREATLAM, a township, joint with Staunton, in that part of the parish of GAINFORD which is in the south-western division of DARLINGTON ward, county palatine of DURHAM, 2 miles (N. E. by E.) from Barnard- Castle. The population is returned with Staunton. Here was anciently a chapel, but no traces of it are discernible. In the neighbourhood are extensive quarries, from which stone has been raised for the erection of the principal buildings in this part of the county; among which is Streatlam castle, a stately structure, built in the seventeenth century, on the site of the old castle, by Sir William Bowes, whose ancestors resided here for many generations.
