Postcard from Denmark!

Today I got a nice postcard from Denmark! The postcard features a view of Kronborg Castle, which is located in Helsingør. The castle originated as one of the strongholds guarding the entrance to the Baltic Sea. It was then transformed by King Frederick II into a castle. It was rebuilt by King Christian IV after a fire had destroyed most of it. The castle is a UNESCO World Heritage Site. Thanks Svea!
