After the
foundation of Gothenburg in 1621, the cannons and other equipment required for the defence of the city were initially kept in storehouses built into the
bastions of the
municipal fortifications, but it soon became clear that these were not of sufficient capacity. The decision to build an additional military storehouse was made in February 1640, and in May 1642 the order was issued to begin construction as soon as the ordered brick from Holland had arrived. The construction work was led by the garrison commander Olof Hansson Swart, later knighted Örnehufvud, who also happened to be the son of the mayor of
Lödöse. The
Riksdag of the Estates (Swedish Parliament) was convened in Gothenburg on 4 January 1660 by King
Karl X Gustav, and the Kronhus was used as a venue for the assembly. The building thus acquired the distinction of serving as the kingdom's parliament house, and the large room on the ground floor has been known as the
Rikssal ('National Hall') ever since. Karl Gustav died suddenly in the Torstensson Palace on 13 February, and the then four-year-old
Crown Prince Karl was proclaimed King of Sweden on 1 March by the Riksdag. In 1669 the
Gothenburg German Church burned down, and the congregation was permitted to hold services in the
Rikssal until the German Church was rebuilt in 1672. In that same year of 1927, the Kronhus was sold by the Swedish state to
Gothenburg Municipality, which initially used it as a general-purpose
storehouse. However, after the
Second World War it was decided to
restore the historic building and turn it into a
museum. The restoration work lasted three years (1954-7), and the Kronhus was officially reopened by King
Gustav VI Adolf on 17 May 1957. The restoration cost one million
kronor and was paid for by private donations. From 1957 to 1996, the ground floor of Kronhuset housed the
Gothenburg City Museum. To commemorate the 300th anniversary of Karl X's death, the Museum held an exhibition in the Kronhus in February 1960, displaying various artefacts related to the king's death, including contemporary pamphlets from Sweden,
Germany and the
Netherlands, and a model of the house in Gothenburg that
Per Brahe the Younger and Beata de la Gardie owned and used as their private hospital during the 1660 Riksdag. The museum has since relocated to the former
Swedish East India Company headquarters at Norra Hamngatan 12. The Gothenburg Wind Orchestra was based at the Kronhus from 1997 to 2020. ==The Building==
