SEATON, a parish in the hundred of COLYTON, county of DEVON, 2 miles (S.) from Colyton, containing, with the chapelry of Beer, 1745 inhabitants. The living is a vicarage, in the archdeaconry and diocese of Exeter, rated in the king's books at £ 17. 0. 7., and in the patronage of Lord Rolle. The church is dedicated to St. Gregory. There are places of worship forWesleyan Methodists and Unitarians. Seaton is situated on the sea coast, and is supposed to have been the Moridunum of Antoninus, and a landing-place of the Danes. Leland speaks of it as having " a notable haven," and of the unsuccessful attempts of the inhabitants " to make a waul within the haven." In 1820, commissioners were appointed, under an act of parliament, to improve the harbour, and the lord of the manor was authorised to take dues. The town has been much improved of late years, and is now a well-frequented bathing-place; a pleasure fair is held on Whit-Tuesday.
