What is "bornholm"

Bornholm (; ) is a Danish island in the Baltic Sea, to the east of the rest of Denmark, south of Sweden, northeast of Germany and north of the westernmost part of Poland. The main industries on the island include fishing, dairy farming, and arts and crafts such as glass production and pottery using locally worked clay. Tourism is important during the summer. There is an unusually large amount of Denmark's round churches on the island.

The island is called Solskinsøen (Sunshine Island) because of its weather and Klippeøen (Rock Island) because of its geology. The heat from the summer is stored in the rock formations and the weather is quite warm until October. But the island received much snow, the most in Northern Europe, in the winter 2010/11 - which lasted from November to April on the island - and all roads were blocked by snow, also on 24 December 2010. Military had to be called in. The island's topography consists of dramatic rock formations in the north (unlike the rest of Denmark, which is mostly gentle rolling hills) sloping down towards pine and deciduous forests (greatly affected by storms in the 1950s), farmland in the middle and sandy beaches in the south.

Strategically located in the Baltic Sea, Bornholm has been fought over for centuries. It has usually been ruled by Denmark, but also by Lübeck and Sweden. The ruin of Hammershus, at the northwestern tip of the island, is the largest medieval fortress in northern Europe, testament to the importance of its location.

Bornholm Regional Municipality, established January 2003 by the merger of Bornholm County with the municipalities, covers the entire island. Bornholm was one of the three last Danish municipalities not belonging to a county — the others were Copenhagen and Frederiksberg. On 1 January 2007, the municipality lost its short-lived (2003 until 2006) county status and became part of the Capital Region of Denmark.

Directly west of Bornholm is Vordingborg Municipality around 150 km (93 mi) across the Baltic Sea on the island of Sjælland.

The Ertholmene archipelago is located to the northeast of Bornholm. These islands, which do not belong to a municipality or region, are administered by the Danish Ministry of Defence.
