for companies to hold smaller conferences inside the fort. Over 10,000 visitors were expected to visit Rödberget Fort in 2002, averaging 300 a day during the summer. Boden Fortress is also still one of the salute batteries of Sweden, which fire a 21-gun salute at special occasions such as the National holiday of Sweden and birthdays of some members of the Swedish Royal Family. The fortress was made a salute battery on 2 June 1931, but since the forts have been decommissioned, the salute is now fired with four cannon located at Kvarnängen in central Boden. Myths and impact Due to the strict security surrounding the garrison, many rumours circulated during the fortress' lifetime. Some were later dismissed as myths or as disinformation, but others were confirmed. One common rumour was that the artillery of the main forts had a range of fire that made it possible to shoot at the important Luleå harbour more than away, but in reality, the maximum range of the farthest shooting pieces was less than half of that. Another widespread myth was that all the forts were connected to each other with a complex system of tunnels beneath the city. However, one has been confirmed, that the forts were used as storage for a large part of the Swedish gold reserve. Around a third of the total Swedish gold holdings of was kept in Degerberget Fort from 1941—transported there disguised as boxes of ammunition—until the last ingots were brought from the fort by six armoured cars in 1982 as the fort no longer was to have around-the-clock surveillance. The total construction cost of Boden Fortress—somewhere around 20 million kronor at the time—would correspond to almost 1 billion kronor (as of 2011) according to the consumer price index which the government agency Statistics Sweden uses. Despite this, the cost has been claimed to correspond to 4 billion kronor of today, and it has also been claimed that the project was more expensive than the JAS 39 Gripen project, which cost 106 billion kronor in total, each aircraft costing between 300 and 500 million kronor depending on what to include in the calculation. No matter what the actual cost was, opinions on Boden Fortress differ markedly, from being called a boastful project and the "JAS project of the turn of the century" to one of the reasons that kept Sweden out of two World Wars.
