According to the 1541 "Annales Bohemorum" by chronicler Wenceslaus Hajek, the thermal springs are fabled to have been discovered as early as 762; however, the first authentic mention of the baths occurred in the 16th century. The settlement of Trnovany was first documented in a 1057 deed, while Teplice proper was first mentioned about 1158, when Judith of Thuringia, queen consort of King Vladislaus II of Bohemia, founded a Benedictine nunnery "ad aquas calidas" ("at the hot springs"), the second in Bohemia. A fortified town arose around the monastery, which was destroyed in the course of the Hussite Wars after the 1426 Battle of Aussig. In the late 15th century, queen consort Joanna of Rožmitál, wife of King George of Poděbrady, had a castle erected on the ruins. The name "Teplice" is derived from the Old Czech, meaning "hot spring".
