The Galle Fort is a pretty beachside destination that is perfect for a day trip while you are staying in Unawatuna. No trip to Galle is complete without taking a look at the Galle Fort which was built in the year 1588 by the Portuguese people who were settled here back then. Afterwards, in the 17th century, the Dutch made a few changes to the structure. Over the many years in Sri Lankan history, a lot of rulers took over this town. Galle is only about 15 minutes away from Unawatuna if you take a three-wheeler.
