Tchefuncte River Lighthouse

The lighthouse has stood at the mouth of the Tchefuncte River since 1837, one of the oldest surviving structures of its kind on the Gulf Coast. It marks where the river meets Lake Pontchartrain — an estuary that covers 630 square miles and drains six Louisiana parishes. The lake receives fresh water from the Tangipahoa, Tchefuncte, Tickfaw, Amite, and Bogue Falaya rivers, along with Bayou Lacombe and Bayou Chinchuba, creating a brackish working waterway that connects interior settlements to the Gulf.

For over a century, this tower guided steamboat traffic into Madisonville. It has survived every major hurricane to hit the North Shore. The Lake Pontchartrain Basin Maritime Museum maintains it now. You can view it from the water or from the museum grounds — a working piece of the estuary's infrastructure, still standing after nearly two hundred years.
