Hans E. Andersin. You can get acquainted with the ancient history of Vyborg by visiting the virtual exposition at our site. The content of the virtual exhibition is identical to the permanent one, "The Swedish Wiborg" that is situated in the Vyborg castle. Our virtual walk through the centuries begins from the foundation of the castle in 1293 and ends in 1710, when Peter the Great conquered the town. Swedish traditions and customs, however, were prevalent in the town for a long time after that.
