of Ems; pop. in 1867, 4,487. It is a very old town, celebrated for the picturesque situation of the superb cathedral of St. George, with seven towers, which exhibits the latest Byzantine architecture in its mixture with the earliest pointed Gothic. It is one of the finest churches in Germany, and was built in the 13th century on the site of one founded in the beginning of the 10th. The town contains a Roman Catholic seminary and other schools, and has manufactories of cloth, machines, and pottery, and a large marble quarry. It was of considerable importance in the middle ages, and possesses a valuable source of the early German history in the so-called " Limburg Chronicle," said to have been commenced in 1336; it was continued down to 1612, and edited by Faust of Aschaffenburg (Worms, 1617), and by Vogel (Marburg, 1826; new ed., 1828). Limburg was next to Wiesbaden one of the principal towns of the former duchy of Nassau.
