The Kalehisar Baths (Castle Rock Baths) are a historic bathing site in Turkey with naturally sulphurous mineral water, whose name suggests a location associated with a hilltop castle or rocky fortress. Sulphurous springs associated with castle sites are found across Turkey, where the same geological activity that produces mineral-rich waters also created the strategic elevated terrain on which fortifications were built, creating a natural coincidence of defensive value and thermal spring in a single location. The sulphurous water of the Kalehisar Baths was long valued within a tradition of mineral spring bathing that reaches back to antiquity, giving these baths a dual identity as both a fortification-adjacent facility and a thermal bathing site associated with well-being.
