After the conquest the Chateau de Ramezay was saved from being a mere fur-trading post by becoming the city residence of the Baron de Longueuil, a Canadian feudal lord, the towers, embattlements and chapel of whose castle were visible on the south side of the river. The founder of this house, which to-day holds the only hereditary feudal barony of Canada, was Charles LeMoyne, who came to Canada in 1642 with Maisonneuve. This man was the son of an innkeeper at Dieppe (France), who it is alleged was descended from a younger branch of the old Norman family of LeMoyne, the head of the house being the Marquis de Longueuil. Fourteen years after his arrival in Canada, LeMoyne received the Seigniory of Longueuil, he having in the meantime amassed a considerable fortune in the fur trade. The eldest son, who was named after his father, was born in 1656, and in recognition of his services at a siege of Quebec, and against the Iroquois, he was made a Baron of France in 1700 by Louis 14th. The old deed of nobility is to this day in an almost perfect condition. An original sketch of the Chateau de Longueuil, taken after a fire which partially destroyed it in 1792, is still in possession of the family. The Chateau, or in reality the Castle, was built by the first Baron in 1699, and for nearly a hundred years sheltered the family of LeMoyne. It stood partly on the ground now occupied by the front of the present parish church of Longueuil, and partly across the highway, at a corner of the Chambly road. The north-west tower was located as late as 1835, but was covered with earth by the excavation for the new church. The Chateau, comprising the chapel, was 210 by 170 feet, and was constructed in the strongest possible manner of stones which were gathered by the river bank. The building was two storeys in height all around, and was flanked by four towers with conical tops. There were high gables over the building, and in the centre a court. On the river-side front it was loop-holed for defence, and it was here that the retainers came in time of trouble. On the west side was the chapel, which was large and extensive. After the fire it was never again occupied, and later on the stone work went to help make the present roadway, as had been the fate of many an Italian palace and temple of Greece. The family gave the land where the present church stands, and they also built the first church, with vaults below. This was done on condition that the family should all be buried there, and so far this has been carried out. The barony was once very extensive, taking in a territory of about one hundred and fifty square miles, including St. Helen's Island, upon which may still be recognized the ruins of the residence which stood on the eastern side of it, Capt. Grant and his wife, Madame de Baronne de Longueuil, having lived there for some time.
