The buildings of the St Helena Light complex are the sole surviving structures on St. Helena Island, in Mackinac County in the U.S. state of Michigan. The lighthouse on the St. Helena Island's southeastern point was built in 1872-1873 and went into operation in September 1873.[8] It became one of a series of lighthouses that guided vessels through the Straits of Mackinac, past a dangerous shoal that extends from the island.[9]
