Oxdjupsleden

Machine-translated from the Swedish article

Oxdjupsleden is a public ferry route across the Oxdjupet strait between Rindö (at Oskar-Fredriksborg) and Värmdö (Stenslätten pier) in the Stockholm archipelago. The Oxdjupet was about 40 metres deep in the 1500s, and the work to fill the depth, for military strategic reasons, with among other things shipwrecks took (with interruptions) about 300 years, until 1839. By the mid-1800s one could walk between Värmdö and Rindö.
