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 Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
