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 Poland. Occupying an area of 588.36 square kilometres, the island had a total population of 39,439 on 1 April 2020.
Among Bornholm's chief industrial activities are dairy farming and arts and crafts industries such as glass production and pottery using locally worked clay. Tourism is also important during the summer months. The island is home to many of Denmark's round churches.
The island is known as solskinsøen because of its weather and klippeøen because of its geology, which consists of granite, except along the southern coast. The heat from the summer is stored in the rock formations and the weather is quite warm until October. As a result of the climate, a local variety of the common fig, known as Bornholm's Diamond, can grow locally on the island. The island's topography consists of dramatic rock formations in the north sloping down towards pine and deciduous forests, farmland in the middle and sandy beaches in the south.
Strategically located in the Baltic Sea, Bornholm has been fought over for centuries.
