[3] Constructed between 1806 and 1809 on behalf of Trinity House in Quebec City, the lighthouse was responsible for the improvement and surveillance of the lower Saint Lawrence River.

[2] The Île-Verte Lighthouse illustrates the expansion of trade and navigation in the early nineteenth century and was an important milestone in the development of a network of safe waterways in Canada.

The Île-Verte Lighthouse served as a prototype for the construction of other lighthouses along the St. Lawrence, by its masonry construction, its cylindrical shape, small size and its overall simplicity.

The longevity of the building and its continued use attest to the success of this design, which proved highly functional, as well as to the quality of materials and construction.

The Île-Verte lighthouse reinforces the austerity of its location on the coast.
