Marienbad, a watering-place in the north-west of Bohemia, about 18 miles south of Carlsbad. The salt springs, yvhich are cold and aperient, were used by no one not living in the locality until the first decade of the 19th century. They belong to the neighbouring abbey of Tepl. The place is now much resorted to both for external and internal treatment, and many bottles of the water are exported. There is a theatre here, and an English church.
