ELSTREE, or IDLESTREE, a parish in the hundred of CASHIO, or liberty of ST-ALBANS, county of HERTFORD, 3 miles (N. by "W.) from Edgware, contaming 309 inhabitants. The living is a discharged rectory, in the archdeaconry of St. Alban's, and diocese of London, rated in the king's books at £8, and in the patronage of the Crown. The church, dedicated to St. Nicholas, was enlarged and new seated in 1824, and received an addition of one hundred and ninety sittings, of which one hundred and sixty-four are free, at an expense of more than £900, of which sum, £250 was granted by the Incorporated Society for enlarging churches and chapels; it is said to have been first erected out of the ruins of the ancient city Suttoniadm, the site and foundations of which are still visible about one mile to the southward. The village stands upon the spot where the old Watling-street crosses from Middlesex into Hertfordshire, and is partly in four parishes, viz. Aldenham, Edgware, Elstree, and Whitchurch. There is a bequest of £5 a year from Robert Warren, for apprenticing one poor child. A National school was established in 1813.
