⛵️ The Old Lighthouse at Presque Isle, Michigan, was built to mark the entrance to Presque Isle Bay and its Harbor. Increasing ship traffic to and past Presque Isle led Congress in 1838 to appropriate funds for a lighthouse. It was built two years later and today is one of the oldest surviving lights on the Great Lakes. The Old Light is located on the waters of NOAA Thunder Bay National Marine Sanctuary and is open to visitors with the Keeper’s House serving as a visitor center and museum. 🎥: M
