(Czech Bilina), a town of Bohemia, Austria, 90 m. N. of Prague by rail. Pop. (1900) 7871, chiefly German. It is a very old town situated on the Biela, and contains a 17thcentury castle, belonging to Prince Lobkowitz. In the vicinity of the towns are extensive lignite mines. Bilin is famous for its mineral springs, the Biliner Sauerbrunnen. They have a temperature of 456° F., and contain a large proportion of bicarbonate of soda. About 4,000,000 bottles of water are exported annually, and another article of export is the salt recovered from the water by evaporation. About 5 m. to the S. of the Sauerbrunnen lies the Bofen or Biliner Stein (1763 ft.), a large mass of phonolite or clinkstone, with rare flora and fine view. The town is indeed surrounded by basaltic rocks, the largest of them being the Radelstein (2460 ft.), from which a fine view is obtained.
