a town of Spain, in the province of Castellon-de-la-Plana, is situated on the S. slope of a mountain, 45 miles N. of Tortosa. It is surrounded by Moorish fortifications, and on the top of the hill stands a strong castle, with a Moorish tower. The streets are steep and irregular, and though many of the houses are handsomely and substantially built, a great part of the town is in a ruinous state. The principal church of Morella, built in 1317, is remarkable for its internal architecture. There are also two other churches, three convents, several schools, a town-house, a theatre, and an hospital. The manufacture of blankets and sashes, which is carried on here, gives employment to 1500 hands; and these articles, together with wheat, form the exports of the place. Morella was taken by surprise in 1838 by Cabrera, who kept possession of the town till it was retaken by Espartero in 1840. Pop. 5180.
