The story of Sundbergs
Sundbergs konditori was founded in 1785 by the confectioner Gustaf Adolf Sundberg. His first shop stood at the corner of Drottninggatan and Klarabergsgatan, where the Åhléns City department store is today. After he was made court confectioner in 1793, he moved the business to Järntorget in Gamla stan, where he already lived.
The café became a haunt of the Skeppsbro nobility, as Stockholm's wealthy merchants were known, and of people from the banks, which earned it the nickname Lilla Börsen, the Little Stock Exchange. It stayed in the Sundberg family until 1944.
The address has even older inn history: in 1605 Meinert Feltman opened the tavern Gripen on the same spot. Today Sundbergs calls itself the oldest café in Stockholm that is still running, and in summer its outdoor tables spread across Järntorget.
