Bazna was documentary attested in 1302. The German colonists established on the western side of the village, on the Rorii Valley, near Boian, and later, when they discovered the beauty of Bazna Valley, they moved here and built an impressive fortified church in the center.
The discovery of the natural gases and of the salty springs with iodine drew the attention of the Transylvanian researchers from the XVIIIth century. Salty water springs have been studied in 1752, for the first time, by the pharmacist Georg Bette from Sibiu, and then by others, too. The priest Andreas Caspari left a manuscript with his observations dating from 1762-1779. He described more therapeutic springs which he baptized “The Church Bath”, “The Beggars’ Bath”, and “The Sour Fountain”.
In 1808 the government from Vienna sent a group of physicians and chemists in Bazna to study the curative effects of the salt and climate. In 1843 four citizens from Medias founded a company whose purpose was to build a resort in Bazna. Two years later, 637 patients were cured in Bazna. In 1905 the Evangelic community took over the resort and transformed it in a “pearl among the Transylvanian spas”. During the same year, people could find here a drugstore and a therapist. At the same time, people started to produce the famous salt of Bazna.

Boian first appeared in documents (“Theodorch de villa Boneti”) in 1309 as the seat of the Archbishop of Tarnava Mica. In 1369 Boian belonged to the Tarnavelor shire and in 1372 the village appeared in documents as “Boyan”, villa Boyum. In 1395 the village belonged to the district of Cetatea de Balta under which remained for a long time. This situation lasted also while Cetatea de Balta belonged to the Lords of Moldavia (starting with Stefan the Great and finishing with Alexandru Lapusneanu); Moldavia’s coat of arms (the bison head) can be seen in the church and on the gate tower.

It was documentary attested in 1359 when it belonged to the Seat of Medias as a free village. The village is cut across by the valley with the same name and is surrounded by wooden hills, with the maximum altitude of 442 meters.
