Westerplatte is a long peninsula at the entrance to the harbour. When Gdańsk became a free city after WWI, Poland was permitted to maintain a post at this location, at the tip of the port zone. It served both trading and military purposes and had a garrison to protect it. WWII broke out here at dawn on 1 September 1939, when the German battleship Schleswig-Holstein began shelling the Polish guard post. The garrison, which numbered just 182 men, held out for seven days before surrendering.
The site is now a memorial, with some of the ruins left as they were after the bombardment, plus a massive monument put up in memory of the defenders.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
