Church of the Cross was a small medieval parish church for the northern part of the Old Town of Oslo. The ruin was rediscovered in 1922 and is now a part of the Ruin Park containing the ruins of the church and the greater St. Hallvard's Cathedral.
There is no definite information about when the church was built. The church is not mentioned in the sources of the fighting in Oslo in 1240 between King Haakon IV and Duke Skule, suggesting that it is possibly younger. In 1989 it was found a stick with runic inscriptions, dated to the first half of the 1200s. The name Church of the Cross occurs in this inscriptions, and it indicates that it may be older than 1240. When the church was built, it was located far north in the city, and an urban development north of the church came in the second half of the 1200s and the 1300s.
Church of the Cross had input from the west, from the cemetery, an entrance from the west and an entrance directly to the chancel from the south. The remains of the original altar foundation is visible. Around the church are the remains of the cemetery wall.References:
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.
