RUHLA, a town of Germany, partly in the duchy of Saxe-Weimar and partly in that of Saxe-Coburg-Gotha. Pop. (1905) 7017. It stretches along the valley of the Erb in the Thuringian forest 8 m. S. of Eisenach, and attracts a number of visitors owing to its beautiful natural surroundings and its mineral springs. Its staple industry is the making of wooden and meerschaum pipes; it has also electrical works, and some small manufactures. Ruhla, which is known locally as Die Ruhl, was famous in the middle ages for its armourers, and subsequently for its cutlers.
