Senneville () is an affluent on-island suburban village on the western tip of the Island of Montreal, Quebec, Canada. It is the wealthiest town in the West Island. Situated close to the city of Montreal, it was historically a popular location for the country houses of wealthy Montrealers. Attractions include multiple golf clubs, a yacht club, and La Ferme du Fort Senneville, an organic demonstration farm. The Morgan Arboretum was founded here in 1953, and is today managed by Macdonald College; an important bird sanctuary, it is open to the public year-round. Fort Senneville was constructed here in 1671, but its ruins are on private land and are not accessible to the public. The historic core of the village was designated a National Historic Site of Canada in 2002. Geography All of Senneville lies over dolomite. In contrast to the monotony of this bedrock, there are many types of soil in the municipality. Clay is common near the northeastern corner and part of the western shores. Sand dominates many inland areas; it is rapidly drained in places but often has impeded drainage due to the type of hardpan which develops in podzols. Near-shore areas along the northern margin have extensive areas of glacial till which forms a calcareous well-drained loam. The loamy slopes overlooking Lake of Two Mountains are excellent for fruit trees and tender plants due to fertile soils, good drainage, and the moderating effect on microclimate provided by the lake. History Because of its strategic location at the far western end of Montreal Island, a stockade fort was built there in 1671. In 1679, Jacques Le Ber, fur trader from Montreal, bought the Boisbriand Fief from Michel Sidrac Dugé, and renamed it to Senneville after Senneville-sur-Fécamp, his hometown in France. Le Ber operated a fur trading post there and built a stone windmill at the fort in 1686, which also served as a focal point for settlers in the area. In 1689, the Battle of the Lake of Two Mountains took place nearby. 1n 1691, the stockade and windmill were burned down by Iroquois and a new stone fort was constructed in 1702-1703, which lasted until 1776 when it was destroyed during the American Revolutionary War by Continental Army troops under Benedict Arnold. The Village Municipality of Senneville was established on January 12, 1895, when it separated from the Parish of Sainte-Anne du Bout-de-l’Isle. The Senneville Post Office
