The Port Burwell Lighthouse is one of the oldest standing lighthouses on the Canadian side of Lake Erie, built in 1840 from local timber. It stands at the edge of the harbour where Otter Creek meets the lake — a modest white tower that looks exactly as you'd hope a 19th-century Great Lakes lighthouse should look. The attached marine museum holds artefacts from the era of sail on Lake Erie: ship models, navigational equipment, and photographs of the vessels that once traded out of this port.
The museum is open in summer months and admission is modest. From the top of the lighthouse there are fine views over the lake and the creek mouth. It's worth combining a visit with a walk along the beach and a look at the HMCS Ojibwa submarine moored nearby.
