Rupelmonde Castle was built by the Counts of Flanders in the 12th century directly opposite the mouth of the river Rupel into the Scheldt river to defend these rivers. It was a large fortress with 17 towers circled by a moat. From this castle toll was levied from passing ships. Later on the castle was also used as a state prison. This caused the castle to play a important role in the history of the region.
In 1678, when Spanish and Dutch troops were fighting against French troops, the castle was destroyed. The castle was never rebuilt and turned into a quarry for cheap building materials for the locals. In 1817 the castle ruins were demolished with exception of a base of a tower with some connecting wall fragments. On these remains then a tower out of red Tournai limestone was built by Baron De Feltz. This tower was used as a hunting pavilion.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.
