It is not allowed to take photos inside the cathedral.... I guess it's because of the noise from the shutter + the annoying flash, which surely disturbs people in their prayers. But since I used my silent little digital camera + I didn't use flash at all, it doesn't count, right ?

There are supposed to be runic inscriptions at 10 places on the second and third floor of the cathedral, ( + 8 on the first floor and 20 on the outside wall ) but I didn't know that when I was there in 2004....
