Mill Ruins Park preserves the foundations, canals, and industrial remains of the flour mills that once made Minneapolis a milling capital. The park sits beside the Mississippi, with the Stone Arch Bridge, Saint Anthony Falls, and Mill City Museum all within a few minutes' walk.
It is best treated as part of a riverfront walk rather than a stand-alone museum visit. The exposed ruins make the city's industrial history visible in a way that the modern skyline can hide.
