The oldest mention of Jedlinka dates back to the 13th century, to the reign of Duke
Bolko I the Strict of the Polish
Piast dynasty. It was a settlement of
lumberjacks, and its name refers to the
fir forests growing here. It was named
Charlottenbrunn by its founder in honour of his wife Charlotte von Seherr-Thossa. In 1737 a spa house and other buildings were built. Later on, the village became a centre of
textile trade. Four
fairs a year took place here. In 1742 the settlement was annexed by the
Kingdom of Prussia. In 1768 it was granted town rights. In the 19th century the
spa town often changed its owners, which slowed its development. In the
interwar period there were six hotels and about 30
pensions in the town. During
World War II, in 1944, the Germans established a
labor camp, which was a branch of the
Gross-Rosen concentration camp, in the town. After
Nazi Germany's defeat in
World War II the region became once again part of Poland and the town was renamed
Jedlina-Zdrój. The
suffix "Zdrój" is typical for names of spa towns in Poland. ==Twin towns – sister cities==
