Spa town with Marconi Sanatorium and circular saline graduation tower to get the full salty experience. The healing properties of Busko-Zdrój's natural waters were discovered in the 12th century. However, the town's development as a spa resort truly began in the 18th century. If the spa isn't relaxing enough then there's always Zdrojowy park for a spot of strolling, cycling, or simply relaxing amidst nature.
