(the ancient Tudela), a city of Spain, province of Navarre, on the Ebro, where it receives the Quieles, 50 miles N.W. of Zaragoza. The Ebro is here crossed by a noble and venerable stone bridge of 17 arches. The town is dull, the streets narrow, crooked, and dirty; the houses lofty and solid. Tudela was made the see of a bishop in 1783. The cathedral, formerly a collegiate church, is an ancient and interesting Gothic edifice with many curious monuments. There are numerous other churches and convents in the town, two hospitals, an orphan asylum, workhouse, prison, and several schools. Manufactures of coarse woollens, hair fabrics, soap, tiles, bricks, and earthenware, are carried on. Pop. 6790.
