Ciechocinek [tx?'tin?k] is a spa town in Kuyavian-Pomeranian Voivodeship, Poland, located on the Vistula River about 10 kilometres (6.2 mi) east of Aleksandrów Kujawski and 20 kilometres (12 mi) south-east of the city of Toru?. It is located within the historic region of Kuyavia.
Ciechocinek is known for its unique[clarification needed] 'saline graduation towers'. Experts have considered the local saline springs to be of extreme value and named the thermal spring no. 14 "a wonder of nature". The therapeutic qualities of these springs are directed toward curing cardiovascular, respiratory, orthopedic, traumatic, rheumatic, nervous system and women's diseases.
The history of Ciechocinek dates back to the Middle Ages. It belonged to the Kingdom of Poland until the Second Partition of Poland in 1793, when it was annexed by Prussia. It 1807 it became part of the short-lived Polish Duchy of Warsaw, and in 1815 it became part of Congress Poland, initially autonomous within the Russian Empire, from 1844 on as part of the Warsaw Governorate. When Wieliczka and Bochnia, towns rich in salt deposits, fell in the First Partition of Poland to Austria, the salt resources of Ciechocinek and nearby S?o?sk drew the attention of Polish officials. On the initiative of Stanis?aw Staszic, a salt extraction project was created. The development of the spa plant and health resort in Ciechocinek dates back to 1836. In 1867 Ciechocinek gained a railway connection with Bydgoszcz and Warsaw. The rapid development and popularity among guests from home and abroad contributed to the granting of town rights in 1916.
After Poland regained independence after World War I in 1918, the spa was taken over by the Polish Government and subordinated to the Ministry of Health. During this period, healing facilities destroyed during the war were rebuilt, new pensions, a post office, school, a residential and commercial complex, the President's Manor House and other facilities were built. The Health Park was also created, consisting of a thermal-saline pool, the Jordan Garden, a sports field and vast green areas surrounding the graduation towers.
Following the invasion of Poland at the beginning of the Second World War, Ciechocinek was occupied by Nazi Germany on 12 September 1939 and on 26 September incorporated into the Reichsgau Wartheland as part of the district/county (kreis) of Hermannsbad (1941-1945). During the occupation the town functioned as a military hospital for German troops and also as a health resort, only for German citizens. The town was liberated from occupation in January 1945. Luckily it avoided significant damage.
In early 2018, a Tesla Supercharger opened, making it the fourth opened in Poland.
