Siege of #Olavinlinna #Olofsborg in by the Royal Swedish Brigadier Baron Hastfehr, in #1788.

I see lots of historical maps so I thought I'd share one of my favorites, even though it is more pragmatic than visually impressive. It presents many roads, castles and water routes for military purposes. Here is Olavinlinna / Nyslott Castle (present day Eastern Finland) from ca. 1581, among letters by Klas Fleming of Lehtis Estate to King John III of Sweden.
