Borkum

Borkum is an island and a municipality in the Leer District in Lower Saxony, northwestern Germany. It is situated east of Rottumeroog and west of Juist.GeographyBorkum is bordered to the west by the Westerems strait (which forms the border with the Netherlands), to the east by the Osterems strait, to the north by the North Sea, and to the south by the Wadden Sea. It is the largest and westernmost of the East Frisian Islands in the North Sea, due north of the Dutch province of Groningen.The island was formed in 1863 by two previously separate islands which were still separated by a shallow water. The seam between the former eastern and western parts is called Tüskendör ("through in between").HistoryMentioned as Burchana fabaria by both Strabo and Pliny the elder, Borkum by the time of Charlemagne was part of a larger island called Bant, which consisted of the present day islands of Borkum, Juist, and the western part of Norderney.
