Bant

Bant was an east Frisian island near the Leybucht. It was inhabited until the 16th century, it's biggest industry being sea salt. The island experienced major floods, which made the island shrink from 76 to 2,5 hectares over it's lifetime, and lead to the salt industry not being profitable enough anymore, therefore the whole population was gone by the 16th century.

The island was entirely submerged by 1780, today only a sandbank remains.
