caption_attribution_description: Dansk: Hammeren Fyr på toppen af Hammeren, det nordligste Bornholm. English: The lighthouse "Hammeren Fyr" at the top of "Hammeren", the northern part of the island Bornholm. The island is located in east Denmark.
context_page_description: Hammeren is a protected area and promontory in Denmark on the northernmost point of Bornholm island. It projects into Sæne Bugt bay in the Baltic Sea. The area includes Hammersø, the largest lake on the island and the only tarn in Denmark, and a hill, 276 feet in height, named Stejlebjerg. It is steep to the southwest but slopes gradually to the northeast, and is separated from the rest of the land by a valley.
context_section_description: Bornholm has varied natural features, such as Almindingen, Jons Kapel, Paradisbakkerne, Rytterknægten, and Dueodde.  Hammeren has cliffs towering 86 feet (26 m) from the Baltic Sea and a rift valley separating it from the surroundings. It covers a rocky area of granite formations (considered one of the best examples of the kind) extending over 182 hectares (450 acres) and including a number of caves. The area, which was once covered with heather and bracken, was laid bare by heavy grazing.
  Hammeren features a large lake, Hammersø, the largest on the island, and a deep pond, Opalsø, surrounded by the rocky slopes of a former granite quarry. Separated by a rift valley, the area is composed of about 50% rocks, 25% forest and 25% cultivated land. All of Hammeren is now a protected nature reserve. There are a number of walking trails connecting Sandvig and Hammershus Slo. The path along the northern rocky face leads to Hammeren Fyr, a lighthouse located at the northern tip, before proceeding along the coastal path towards the south east to the harbour, Hammeren Havn.
