On our tour of Slovenia's Piran, we also peeked on the Croatian side, and had a swim in the Polynesia Beach in the town of Umag. Little did we know that the ruins we started our swim from were actually the ruins of the Sipar Castle from A.D. 1000 or thereabouts. Some have even called this place the Atlantis of Sipar. Interesting!
Apparently Sipar Castle was built by sea-faring pirates. Today, the area looks like a thin small peninsula, or perhaps the ruins of a unmaintained pier.
Nice swim, by the way! Very warm water. Maybe even too warm. Our swims in Lake Bled and Lake Bohinj were more refreshing!
The coordinates for the ruins on the beach are N 45.467779 E 13.507431.
