HODDESDON, a market-town and chapelry, partly in the parish of GREAT-AMWELL, but chiefly in that of BROXBURN, hundred and county of HERTFORD, 4 miles (S. E.) from Hertford, and 17 (N. by E.) from London, containing 1354 inhabitants. The name of this place is supposed to have been derived from its having been the residence of Hodo, or Oddo, a Danish chief, or from a tumulus, or barrow, raised here to his memory. The town consists principally of one street, extending along the high road from London to Ware and Hertford; it is supplied with water from a conduit in the market-place, erected by Sir Marmaduke Rawdon in the seventeenth century. A considerable quantity of malt is made here, much of which is conveyed to London by means of the river Lea; and there is a large brewery. The market, now nearly disused, is on Tuesday; and a fair is held annually on the 29th of June. In the centre of the town is an ancient market-house, built of wood, and supported on pillars and arches ornamented with curious carving. The site of the old chapel, dedicated to St. Catherine, is marked by a turret, which serves as a clock-house, and which, having become ruinous, was rebuilt about 1730. The present chapel is a handsome brick edifice, standing in the parish of Amwell, but subject to the vicarage of Broxburn; it has received an addition of eight hundred sittings, four hundred of which are free, the Incorporated Society for the enlargement of churches and chapels having granted £700 towards defraying the expense. Here are places of worship for the Society of Friends and Independents. Queen Elizabeth, in the second year of her reign, granted a charter for a free grammar school, with considerable privileges; and there is a National school for ninety boys and thirty girls, supported by voluntarycontributions. Five ahnshouses, founded in the fifteenth century, are now under the management of the parish officers.
