Yes, you can see the Helsinki (Lutheran) Cathedral and the Uspenski (Eastern Orthodox)Cathedral from the Port of Katajanokka. Uspenski is the largest Orthodox church in Western Europe. Ah, Western Europe, the euro zone, mozzarella sandwiches, high speed trains without the clickety-clack, "Hei! Hei!" from sales associates - oh, how civilized the weekend was.
I spent the last hour of December 31, 1999 and the first hour of January 1, 2000 - the first hour of our current millennium - on the steps of the Helsinki Cathedral. I discovered fireworks laws were a little more liberal in Finland (as well as alcoholism laws) as I was stuck underneath a tall man's outstretched arm holding a canon that launched colorful balls of explosives.
