BELVOIR, (Lincolnshire) or BEVER-CASTLE, as it is commonly called, 4 m. from Grantham, and 83 from London, was, according to Camden, and others, built by Robert de Tedenci, or Tetencio, a noble Norman, to whom William the Conqueror gave this, and 30 other manors in this Co. and who erected a priory near it, which was a cell to St. Albans in Hartfordshire. It afterwards came to the family of Ld. Roos, or Ross; from whom, by marriage of a female heir, it passed to Sir Robert Manners, whose son, the E. of Rutland, rebuilt the castle, which had been demolished in the R. of Hen. II. and it has continued the seat of that family, who are now Ds. of Rutland, ever since: and a very magnificent one it is, this noble family having, for several generations, spared no cost to render it delightful, so as to answer its name, for it affords a charming prospect into the Cos. of Nottingham, Derby, Leicester, Rutland, and Northamptonshire, as well as over the fruitful valley under it, which, for the most part, bel. to the D. and spreads from this Co. into those of Leicester and Rutland. In the fine gallery of this noble seat are fine family, and other pictures, buth ancient and modern; particularly the original one of K. Ch. I. as he sat at his trial.
