Bergenhus Fortress
Medieval fortress located in Bergen, Norway

Bergenhus fortress (Norwegian: Bergenhus festning) is a fortress located in Bergen, Norway. Located at the entrance of Bergen harbour, the castle is one of the oldest and best preserved stone fortifications in Norway.
History
The fortress contains buildings dating as early as the 1240s, as well as later constructions built as recently as World War II. The extent of the enclosed area of today dates from the early 19th century. In medieval times, the area of the present-day Bergenhus Fortress was known as Holmen and contained the royal residence in Bergen, as well as a cathedral, several churches, the bishop's residence, and a Dominican monastery. Excavations have revealed foundations of buildings believed to date back to before 1100, which might have been erected by King Olav Kyrre. In the 13th century, until 1299, Bergen was the capital of Norway and Holmen was thus the main seat of Norway's rulers. It was first enclosed by stone walls in the 1240s.
Of the medieval buildings, a medieval hall and a defensive tower remain. The royal hall, today known as Haakon's Hall, was built around 1260. The defensive tower, was built around 1270 and contained a royal apartment on the top floor.
