Kastellet, which sits near the heart of Copenhagen, Denmark is one of the best preserved fortifications in Northern Europe. It is constructed in the shape of a pentagram and was originally started back in the 1600's. The King's Gate sits on the south side of Kastellet and faces the city. I came across it while wandering around the area near The Little Mermaid statue. That's one thing I love about Europe - there is just so much history to explore, and you can find the neatest things just by wandering!
