The Wydah Pirate Museum in Cape Cod MA - it's a smaller museum but it's packed full of artifacts recovered from the wreck of an actual golden age of piracy ship (the Wydah, Black Sam Belamy's ship which wrecked in Cape Cod). They have multiple weapons, cannons, and the only confirmed pirate treasure ever recovered. All the artifacts were just super cool, very few recreations of things almost everything is really from the actual wreck. The excavation of the wreck site is ongoing too, the last room in the museum is dedicated to showing how they recover items that have been encased in "concretions" and has lots of items actively being recovered so you can see the process happening.

Idk, I'm a golden age of piracy nerd for sure so this was super cool to me.
