Annenkrone

Annenkrone (St Anne's Crown, Russian: Анненские укрепления, tr.

Annenskiye ukrepleniya, Finnish: Pyhän Annan kruunu) is an early 18th century fortification in Vyborg, Russia.

[1] The project was under the direction of the German-born soldier-engineer Burkhard Christoph von Münnich.

[2] Annenkrone is composed of four bastions and three ravelins facing west and one moat on the north side.

After the Finnish War of 1808–1809 Annenkrone lost its significance as Finland became a part of the Russian Empire and the border against Sweden was transferred hundreds of kilometres west.
