Eisenach (I'zen-ahh), a town of Saxe-Weimar, is beautifully situated at the north-western verge of the Thuringian Forest, 69 miles by rail SE. of Cassel, and 49 W. of Weimar. It has a ducal palace (1742), now used as a court-house; a spacious market-place, and manufactures of art pottery, leather, etc. Bach, of whom a statue was erected in 1884, was a native; and Fritz Renter died here in 1874. Population, above 31,000. On an eminence rising 600 feet above the town, engirt by forests, stands the Wartburg, founded in 1067, and till 1440 the castle of the Landgrave of Thuringia. It is famous as the spot where the Minnesingers assembled to hold a poetic contest ('the war of the Wartburg') about 1207; as the home of St Elizabeth (1511-27); and as the ten months' asylum to which Luther was carried by the Elector of Saxony (May 1521). The chapel in which Luther preached, and the chamber in which he discomfited the Evil One by throwing the inkstand at his head, are pointed out. The pile was magnificently restored in 1847-70.
