The Vyborg town wall (Russian: Выборгская городская стена, Finnish: Viipurin kaupunginmuuri, Swedish: Viborgs stadsmur) was a defensive structure built around the town of Viborg (today Vyborg, Russia).
It was completed during the Swedish era in the 1470s and demolished mainly in the 1860s as Vyborg was a part of the Grand Duchy of Finland.
Some minor parts of the wall are still preserved as well as two round towers.
The wall was 5–6 meters high and had originally 10 towers with a combination of circular and square designs.
[1] According to legends, one of the towers exploded during the Russo-Swedish War in 1495 and the Russian invaders escaped in great fear.
