Passage: Alingsås was founded as inhabitants from the city Nya Lödöse were made homeless as Danish troops burnt it down. Gustavus Adolphus granted Alingsås its Royal Charter in 1619, which makes it older than Västra Götaland's largest city—Gothenburg which was granted its charter in 1621.Among its historical inhabitants is Jonas Alströmer, who was born in Alingsås in 1685. Alströmer is credited for introducing the potato plant to Sweden. He also established a large scale draper's industry there, which before long became Sweden's largest. However, some too-optimistic calculations, devastating fires and political setbacks finally forced its closure in 1779.Alingsås is known for its cafes, 26 in total (in 2010).
