The Ann & Gabriel Barbier-Mueller Museum: The Samurai Collection

You can see some seriously intricate samurai armor and weapons at this museum exhibit, with a focus on the ironwork that went into making these pieces—think detailed metalwork and craftsmanship you don't usually get to examine up close. It's called "Iron Men: The Artistry of Iron in Samurai Armor" and admission is free, so you can check it out without committing your whole day.
