in 1536 by Fräulein Maria von Jever. They stand for "Donat Urbi Maria Gubernacula", meaning "Mary gives the power of government to the town" in Latin. The flag and banner can be described as such: "The flag or banner is blue-and-white-striped horizontally or vertically, with the coat of arms in the middle." Twin cities Jever is twinned with the following cities: Zerbst, Germany (1990) Cullera, Spain (1998) Geography Geographical location and neighbouring municipalities Jever is situated in Jeverland, part of the north-eastern part of the East Frisian peninsula, and is located near the coast of the North Sea in Lower Saxony, some 15 kilometres west of Wilhelmshaven and Jade Bight. Jever borders the municipality of Wangerland to the north, the town of Schortens to the east and south, and the town of Wittmund to the west. In the southwest, Jever briefly borders the East Frisian municipality of Friedeburg. Urban structure Since the local government reorganization of 1972, the town consists of the core town of Jever, into which the previously independent suburban area of Jever had already been incorporated in 1844, as well as the districts of Moorwarfen, Rahrdum, Cleverns, Sandel and Sandelermöns. Geology The town is situated on a flat tongue of the Oldenburg-East Frisian geest, which rises 7 to 8 metres above the surrounding flat marshes of the Wangerland. The foothills were formed by sand deposits during the Ice Age. The Cleverns district is a typical landscape with a geest culture, which can be seen in the wall hedges. Towards the town border with Schorten, Jever has bogs which are protected under conservation. Major bodies of water Jever is surrounded by several interconnected tiefs. (A tief is a watercourse close to the sea, the bed of which is generally or largely below mean sea level. They are mainly used to drain lower areas behind dikes.) These include the Moorlandstief in the east, the Mühlentief in the west, and the Tettenser Tief and the Hooksieler Tief in the north. All of the tiefs in Jeverland flow into the North Sea via the Hohenstief Sieltief in Horumersiel. Lake Moorwarfener, a former quarry pond which is managed by the Jever Fishing Club, is also located in the town area. The lake is located in the Jeveran district of Moorwarfen and covers around 17 hectares. Climate Jever has a temperate climate, under the direct influence of the North Sea. Daytime temperatures are
