Noyon (anc. Noviomagus), a town of France, in the department of Oise, 55 m. N. E. of Paris; pop. in 1866, 6,498. It is a place of great antiquity, and was the birthplace of Calvin. The cathedral of Notre Dame, built by Pepin the Short, enlarged by Charlemagne, and, after having been damaged by fire, rebuilt in the 12th century, is one of the best specimens of transition architecture in France. There are several other fine public buildings, among which are the town hall, the ancient episcopal palace, and the hospital. There are manufactures of cloth, laces, and hosiery. Charlemagne was here crowned in 768, and Hugh Capet was here chosen king in 987. The place subsequently passed through many vicissitudes. In 1516 a treaty was concluded here by Charles V. and Francis I. - About 4 m. E. of Noyon is the village of Salency, with a palace and an ancient church. It is the birthplace of St. Medard, who instituted here a "festival of roses," which is still celebrated by crowning the most virtuous maiden of the village, and presenting her with a sum of money.
