To celebrate 130 years of service, the Port Sanilac Lighthouse is open to the public from 10 a.m. to 6 p.m. Saturday, Sept, 10. The lighthouse is located on South Lake Street. With the completion of major restoration work, the public can see the original 1886 classic lighthouse Fresnel lens in place on top of the tower before the U.S. Coast Guard replaces it with a new LED light the following week.
