A 18th-century fortress once a symbol of Sweden's military might, now a hotel

Hidden away in the Stockholm archipelago, Fredriksborg Fortress is a relic of another time. Completed in 1735, it was one of a defensive system built to protect Stockholm after Russian raids in 1719. Named after King Fredrik I, this imposing fortress was meant to defend the inlet to Stockholm. In the center of the tower, a huge powder magazine was built. Ammunition was stored here, around which living quarters, heated with four open fireplaces, were built.

High above the water, the tower provided artillery with better protection and a higher concentration of fire. In the late 1700s, the tower was used as a link in an optical telegraph system that was situated on the roof. Today, a reconstruction of this system can still be seen. In 1770s, maintenance on the fortress was necessary due to neglect. Fredriksborg lost its importance according to the determinations for Sweden’s fixed defense in 1822.

Today, Fredriksborg Fortress is a protected building and has been transformed into a hotel and restaurant, opening its doors to visitors during the summer months.
