NEMPNETT-THRUBWELL, a parish in the hundred of KEYNSHAM, county of SOMERSET, 9 miles (N. E. byE.) from Axbridge, containing 264 inhabitants. The living is a perpetual curacy, annexed to the rectory of Compton-Martin, in the archdeaconry of Bath, and diocese of Bath and Wells. The church is dedicated to St. Mary. Within the parish is a large tumulus, of an oval form, the finest in the kingdom, on opening which in 1789. it was found to contain two rows of cells, running from south to north, formed by immense stones set edgeways, and covered with others of still larger dimensions. Sculls, a vast heap of bones, and other relics, having been discovered, it is conjectured to have been a work of the Druids, and to be the cemetery belonging to their great temple at Stanton-Drew, three miles off. An old mansion, in this parish, called Reghillbury, where Sir William Wyndham spent the period of his retirement from public life, is supposed to have been once a royal palace.
