W. of Spires, and at the junction of railway lines to Worms, Weissenburg and Monsheim. Pop. (1905) 18,576. It has four churches, two Evangelical and two Roman Catholic. The Protestant abbey church, a fine Gothic edifice dating from the 14th century, contains the tombs of several of the counts palatine of the Rhine. The Roman Catholic Ludwigskirche is a modern Gothic structure. The chief industries of the town are cloth, paper, furniture, soap, starch and hats. It has also breweries and distilleries. A brisk trade is carried on in wood, grain, fruit and wine, all of which are extensively produced in the vicinity. Neustadt, which became a town in 1275, is one of the centres of the Rhenish "grape-cure," and thus attracts numerous visitors.
