Bosch (in Dutch; Flemish pronounced as /bɔs/) was a West Frisian island in the Wadden Sea. It was situated off the coast of present-day Groningen in the Netherlands, between the islands of Schiermonnikoog and Rottumeroog.[1]
Between 1400 and 1570 CE, the island Monnikenlangenoog had split into the islands Bosch and Rottumeroog.[2] Bosch disappeared in the Christmas Flood of 1717.[1] A shoal named Boschplaat was the remnant of the island, which merged into Rottumerplaat in 1959.
