The industrial history of Alingsås began in 1724 when Jonas Alström established there a factory. The factory had 1,000 employees already in the mid-18th century. The Alströmerska warehouse at the Lilla Torget is the city’s oldest secular building. It was built in the beginning of the 1730s and is the only property left from the Alströmerska époque. The building was first used by Jonas Alströmer to house materials used in manufacturing. In 1928 the museum took over the building and at first shared it with the library that is now located next door.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
