Kvarven Fort was a mountain fort strategically located by the main shipping channel of the Byfjorden leading to Bergen, Norway. Construction In the late 1800s, relations between the two countries in the union between Sweden and Norway had gradually worsened. Norwegians were discontented and wanted independence. In case of a violent dissolution of the union, new coastal defenses were built. In Bergen, several forts were built to defend the harbour and the naval installations at Marineholmen and Wallemsviken from Swedish seaborne attacks. Kvarven fort was one of these, along with Hellen Fort and batteries in Sandviken. Construction of Kvarven Fort began in 1895. The military bought the nearby farm Bakke in 1898, and turned its stately main building into the commander's quarters. The fort construction was completed in 1899. An additional torpedo battery was in place by 1902. This and the Howitzer L/14 cannons made Kvarven a very modern fort for its time, though it did not have to fulfil its intended use as the union with Sweden dissolved peacefully in 1905.

World War II Norway attempted to maintain neutrality during World War II as well, but was invaded by the Germans in their Operation Weserübung on April 9, 1940. The Bergen part of the operation was fronted by cruisers and , with a total of 1,900 German soldiers. Kvarven fort was manned by 33 officers and 279 corporals and privates with an average age of around forty. The fort failed to open fire at the first German ships of the invasion force, mistaking the armed trawlers Schiff 9 and Schiff 18 for unarmed merchant ships. When the fort finally opened fire at 3:58 in the morning, it only managed to get off a few shots through the fog at two torpedo boats and the cruiser Köln. The ships did not retaliate, but sent a morse coded message in English saying “stop shooting!“. Only the third wave of German ships were taken under effective fire by Kvarven. The fort first hit Bremse twice, then the MTB mothership Carl Peters once, compelling both ships to break off their attempt to force their way into the harbour. After these ships, the cruiser Königsberg tried to break through and was hit by three shells: one beneath the waterline,
