Basen termalno-solankowy w Ciechocinku, Thermal saltwater pool in Ciechocinek, Poland

Basen termalno-solankowy w Ciechocinku is a public thermal pool in the Polish spa town of Ciechocinek, filled with saltwater drawn from deep underground mineral sources. The water is naturally heated and has a high mineral content, which sets it apart from ordinary swimming pools.

The saltwater pool opened in 1932, designed by Romuald Gutt and Aleksander Szniolist, with President Ignacy Mościcki attending the ceremony. It was listed as a historic monument in 1993. On 15 September 2001 the town closed it due to poor technical condition; it later changed owners several times, and plans for a hotel or a Jordan garden were never realised.

The pool's name links it to Ciechocinek's brine springs, and its 1932 opening drew President Ignacy Mościcki. Closed since 15 September 2001, the empty basin now draws visitors who come to see the architecture of Romuald Gutt and Aleksander Szniolist rather than to bathe.

The pool has been closed since 15 September 2001, so it can only be viewed from outside, along aleja Pojednania. It is listed in the monument register, and its basin and surrounding structures stand unused while successive owners consider redevelopment plans.

The pool has been closed since 15 September 2001, when the town authorities shut it because of its poor technical condition. It was entered in the register of monuments in 1993, and later plans for a hotel and a Jordan garden on the site were never carried out.
