The Historic Sausage Kitchen of Regensburg (Wurstküche) is notable as perhaps the oldest continuously open public restaurant in the world. In 1135 a building was erected as the construction office for the Regensburg stone bridge. When the bridge was finished in 1146 AD, the building became a restaurant named Garkueche auf dem Kranchen ('cookshop near the crane') as it was situated near the then river port. Dockers, sailors and the staff of the nearby St. Peter cathedral workshop were the regulars for the centuries to come. The present building at this location dates from the 17th century, but archaeological evidence has confirmed the existence of a previous building from the 12th century with about the same dimensions.
Until ca. AD 1800, the specialty was boiled meat, but when the family who currently own the restaurant took over in 1806, charcoal grilled sausages were introduced as the main dish offered. The kitchen still operates today and serves 6,000 sausages to guests daily.References:
The small Grisslehamn village is today a well-preserved sample of 19th century architecture and popular attraction for daily trips. The name Grisslehamn was first mentioned in a document from 1376 about the mail route between Sweden and Finland. This Grisslehamn was located some 20 km south of today's location. In the mid-18th century, most of the old village was destroyed in a fire, and it was decided to move Grisslehamn to its current location to make the mail route shorter. Conveying mail by row boat from Sweden to Åland, from whence it was transported to the Finnish mainland, was, together with fishing, one of the most important sources of income for the inhabitants of Grisslehamn and other parts of Roslagen for a long time, until steam ships took over the mail routes in the early 20th century.
During the Finnish War in 1809 a small unit of Russian cossacks attacked to Grisslehamn over the frozen Gulf of Bothnia. In the battle 80 Swedish soldiers surrended and several were killed.
Today there are several buildings dating from the 19th century, like the toll station and old barracks. The post office was built in 1755 and the chapel in 1909.
