History & facts

Fredriksborg is a fortification construction on Värmdö close to Oxdjupet, the inlet to Stockholm. The fortress, and the buildings surrounding it, was built to protect Stockholm against foreign enemies who came closer after the Great Nordic war 1700-1721.

In 1724, based on blue prints made by general Axel Löwen, the construction commenced. This would be the ultimate defence for Stockholm: situated 40 meters above the sea and equipped with rifle – and cannon artillery. The fortress was surrounded by a ditch and could only be reached by a drawbridge, which is still intact today.

The building of the fortress was finalized in 1735 and was named Fredriksborg Fortress after King Fredrik I. It was considered the strongest fortress in Europe.
