Harbour

Hamn is a battlefield museum in Fisksätra dedicated to the Battle of Stäket on 13 August 1719, a pivotal clash in Nacka's history that you won't find covered like this anywhere else nearby. The vibe is welcoming and unhurried, with staff who actually love talking about the history, and it works just as well for kids as it does for history buffs. There's parking on site, so it's easy to just show up.
