St Olaf's Castle in -25 C

My traditional Christmas Day visit at my aunts in my hometown. I started my trip early in the morning to have some time for geocaching. I was in town just at the time of sunrise (9:30 am) and went find one geocache in these views. This medieval castle is called Olavinlinna (St. Olaf's Castle) has been built 1475 on the rock island locating in the middle of the flowing water.
