Akershus Fortress by Night

I've blipped this castle a number of times before, but this is the first time by night.

The building of Akershus Castle and Fortress was commenced in 1299 under king Håkon V. The medieval castle, which was completed in the 1300s, had a strategical location at the very end of the headland, and withstood a number of sieges throughout the ages. King Christian IV (1588-1648) had the castle modernised and converted into a Renaisssance castle and royal residence. During the 17th and 18th century the castle fell into decay, and restoration work only started in 1899.

Some dark chapters in history were written here during WWII when the castle was used as a prison.
