The town of Hartlepool stands on a small peninsula on the southern coast of Durham, and is about nine miles north-east of Stockton-upon-Tees. From the "Slake," or Pool, which is between the town and the mainland to the west, it probably received the appellation of "_Le Poole_," to distinguish it from the village of Hart, which is about four miles and a half to the north-west. The word Hart, according to Ducange, signified, in Teutonic, a forest; and, if the name of the parish of Hart be of the same origin, the reason why the place should have been so called is obvious. The old town-seal of Hartlepool contains a rebus of the name--a hart up to his knees in a pool--which assigns to the first part of it a different etymology. Previous to receiving the name of Hartlepool the place was called Heortu, and sometimes Heortness; the terminating _u_ is perhaps an abbreviation of _eau_, water; and the name Heortu synonymous with Hart-le-pool. The termination _ness_ is expressive of the place being built on a point of land which projects into the sea. "At or near this place," says Bishop Tanner, in the _Notitia Monastica_, "was the ancient monastery called Heorthu, founded upon the first conversion of the Northumbrians to Christianity, about A.D. 640, by a religious woman named Hieu, or, as some have it, St. Bega, whereof St. Hilda was some time abbess." This ancient convent was destroyed by the Danes about 800, and its site is now unknown, though it is supposed to have stood on the spot which was subsequently occupied by a Franciscan monastery, founded by one of the Bruce family about 1250, and suppressed by Henry VIII. Of this monastery or its church there is at present no part remaining, though some old houses, called the Friary, probably built out of the ruins, still indicate its situation. The church of Hartlepool, which is dedicated to St. Hilda, is a large building, and, from the various styles of its architecture, has evidently been built at different periods. About the time of the Conquest, the manors of Hart and Hartness belonged to Fulk de Panell; and, upon the marriage of his daughter Agnes with Robert de Brus, one of the Norman followers of William I., they came, with other rich manors in Yorkshire and in Durham, into the possession of that family. Upon Robert Bruce, a descendant of the above-named Robert de Brus, succeeding to the crown of Scotland in 1306, all his English estates were confiscated by Edward I., who granted the manor of Hart and the borough of Hartlepool to Robert de Clifford, "saving the rights of the Bishops of Durham," under whom, since 1189, the property had been held.
