Īle aux Coudres was named by Jacques Cartier in 1535 for all of the coudriers (hazelnut trees) he found there. Today, the island has many farms and is refreshingly laid back when compared to Quebec City, just sixty kilometres away.
On the northwest side of Īle aux Coudres, across the water from Baie-Saint-Paul, stands Pointe de la Prairie Lighthouse, which was built in 1972. The point gets its name from the prairie-like marshland that extends from this part of the island. The tower is a white circular pillar, with a red lower portion and surmounted by a helicopter pad. Standing seventeen metres high, with a focal plane of 15.6 metres, the light receives power through an underground electric line and directs marine traffic through the St Lawrence River north shipping channel. In 2004, after years of exposure to severe conditions of salt water, continuous freeze-thaw cycles and ice flows, the base, which was beginning to crumble, was reinforced with a shotcrete mix composed of silica fume, steel fiber, granite aggregate, air entraining admixture, and a set time accelerator.
The first offshore lighthouse to mark this point was constructed in 1931 and was known as Īle aux Coudres Lighthouse. This white lighthouse rested atop an octagonal mass of concrete on the north edge of Prairie Shoal and resembled a wedding cake. A fog alarm was housed in the bottom floor of the lighthouse. The keeper's quarters were located in the second level, and the structure was topped by a lantern room.
The first keeper of Īle aux Coudres Lighthouse was J. Pedneault. No keepers were ever assigned to the present tower.
Keepers: J. Pedneault (1931 - at least 1937).
