Me and the wife wandered around the Splitrock lighthouse north of Duluth last month. The Minnesota Historical Society has done a great job preserving the lighthouse, grounds and even the mechanism that turns the lamp. The North Shore and Isle Royale are some of my favorite places on the planet.
I have an original steel cut engraving of the bay before the lighthouse and a black and white photo of it just after completion. ( side by side on the wall for comparison)
