The Flowerpot Island Lighthouse is located on Castle Bluff, on the northeastern point of Flowerpot Island, a medium-size, uninhabited island near Tobermory on the west side of Georgian Bay. The present Flowerpot Island Lighthouse was built in 1969 and is the second to be erected on the site.
There are four related buildings on the site that contribute to the heritage character of the lighthouse: the 1963 Boathouse, the 1901 Lightkeeper’s Dwelling, the 1959 Assistant Lightkeeper’s Dwelling, and the Observation Deck Building.
The lighthouse is also part of the Fathom Five National Marine Park and is staffed by volunteers, who maintain the lightstation and provide interpretation services for the large number of visitors to the site.
