For the past two nights, I stayed in one of the strangest places in my whole trip: an army barracks in a Prussian fortress built in the 1840s, called Boyen Fortress. It was on the edge of a town called Giżycko in the Masurian Lakes region of northern Poland. In the nineteenth century, the area was part of the Prussian empire close to the border of its rival Russian empire.
The building has been turned into a hostel but all that seems to mean is that they take your money and provide some sheets for the bed and that's all. It's probably popular in summertime but at this time of year I was the only one staying there. At first the idea seemed pretty cool, but when I returned to the barracks on my first night to a completely empty fortress (except for one security guard and a dog) the quiet hallways were eerie. I started wondering if it might be haunted by Prussian soldiers or by Nazi soldiers - it was occupied by the Germans during the second world war. It was also extremely cold, but since I was the only one there I could take a second duvet from one of the other beds. I managed a second night there but am glad to have left and found a nicer hotel to stay in.
