The real centre of Naleczow is the extensive and charming spa park, with its great selection of tree types and distinguished by several monumental sanatorium buildings and the Malachowski Palace. The heart of the park is, of course, the lake. There are both historical and modern sanatoriums as well as places to stay located on the border of the park, enveloped by lush greenery. The town’s main avenues are flanked by numerous old trees and there are many painstakingly renovated wooden villas and other residences, many of which are of architectural interest. The parish church, on the edge of the town, has an interesting cemetery beside it.

Since the 19th century, Naleczow has been a favourite place to visit and to work in for several famous Polish writers: Zofia Nalkowska, Henryk Sienkiewicz, Stanislaw Przybyszewski, Stanislaw Witkiewicz, Stefan Zeromski and Boleslaw Prus. The last two have museums in Naleczow devoted to their literary achievements.

While the climate continues to be an important factor in the treatment provided in Naleczow, today the full range of possibilities offered by modern balneotherapy is used in the care of patients with circulatory system diseases. The therapeutic properties of the natural mineral water, whose chemical composition can be compared to the spa waters, have been highly appreciated for the past two centuries. Naleczow mineral water is bottled and available as the well-known “Naleczowianka” and the lesser-known “Cisowianka” brands.
