The first written record of Raikküla manor date back to the year 1469. Later it has been associated with the von Staals, the Kankrins and the von Keyserlings. The luxurious High-Classicist main building was completed on the foundation of a former building in 1820. After a fire in 1960, the house lied in ruins for a long time. Currently, it is privately owned and being renovated. About a kilometre from the manor's centre is a family graveyard of the von Keyserling's family.

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.
