BOROUGHBRIDGE, a hamlet situated within the parishes of LING, OTHERY, MIDDLEZOY, and WESTON- ZOYLAND, partly in the hundred of ANDERSFIELD, and partly in that of WHITLEY, county of SOMERSET. The population is returned with the respective parishes. Collinson, the county historian, considers the name to be derived from " a large borough or mount, very high and steep," and a stone bridge of three lofty arches, which here crosses the navigable river Parret: this mount is situated within an enclosure on the eastern side of the river, and has generally been thought to have been formed by nature j but the same author supposes it to be a work of art, raised for a tumulus. It is crowned with the ruins of an ancient cruciform chapel, which was dedicated to St. Michael, and dependent on the abbey of Athelney. Though previously in a dilapidated state, it was greatly damaged during the parliamentary war, when it was occupied as a military post by a small party of royalists, who, after having successfully resisted various assaults, were compelled to surrender to a body of parliamentarians, detached against them by General Fairfax.
