Museo dell'Acqua e dei Mulini ad Acqua

This museum dives into the history of Trapani's legendary salt flats, housing original wooden mill paddles (ntinni), vintage tools used by salt workers, and striking black-and-white photographs that bring the industry's past to life. It's a surprisingly engaging stop — the kind of place where you leave knowing something real about how this corner of Sicily was shaped by salt, wind, and water.
