The Port of Helsinki in Finland is almost every winter icebound.
The cruise ships and ferries entering the port will pass the Fortress of Suomenlinna through the fractured ice via narrow Kustaanmiekka strait which leaves no extra space for big ships.
Remember the passport control, if you are sailing under foreign flag.
The fortress has a beautiful star-shape which is clearly visible only from the see and and at the deck of a big ship.



Great photos. It seems we have both been to Suomenlinna recently.
Thanks Debra!
We have, though last Tuesday I only passed it. I was walking there in December, maybe I should post something from that visit too …
