Virstantolppa is the oldest memorial in Lappeenranta. It stands in the site of remarkable battle in Russo-Swedish war in 1741. Over 4000 men were killed or injured in the battle on 23th August 1741 where Russian army conquered Lappeenranta. The battle was one the bloodiest in time. Two Swedish commanders were executed in Stockholm afterwards because of serious defeat.
The memorial was erected originally in 1818 and enhanced in 1924 and again 1949.
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.
