This small bridge is always interesting to look at because it blends in well with the surroundings. The two elements on the left and right are made of solid stone, while the bridge itself is constructed of wood.

Nestled in the forest above Nøklevann, Sarabråten was once the summer estate of Christiania’s 19th-century elite, hosted by timber baron Thorvald Meyer. Today, only a few ruins remain, but the place still carries a quiet grandeur, perfect for a reflective pause in the woods.
