Ormond Plantation House, Creole plantation house in Destrehan, St. Charles Parish, Louisiana, United States

Ormond Plantation House is a French Colonial Creole plantation house in Destrehan, St. Charles Parish, Louisiana. Its front and rear walls were built in the late 18th century of brick between cypress posts (briquettes entre poteaux), with adobe filling on the side walls. A gallery with rounded cement and brick columns runs along the front, and wood columns on the second floor support the roof. Two taller garconnieres, or bachelor quarters, flank the main block.

The plantation was established in the late 1780s by Pierre Trépagnier, who received the land from the Spanish government in recognition of his service during the American Revolution. Richard Butler purchased the property in 1805 and gave it its current name, while the plantation experienced changes in ownership and shifted between sugar and rice cultivation.

The house took its name from a castle in Ireland, honoring the Irish roots of its former owner Richard Butler. This naming reflects how the plantation connected distant lands and the families who made it their home.

The house stands in Destrehan, St. Charles Parish, between the Mississippi River and Lake Pontchartrain. The two garconnieres, taller than the main block, were joined to it when the carriageways were enclosed during the 1943 restoration, so look for that seam. The Browns also added indoor plumbing, natural gas and electricity.

In 1798 Pierre Trépagnier left a family meal to meet a caller whose coach bore Spanish insignia; servant and master both vanished, never seen again. The garconnieres, taller than the main block, may date from 1811 under Richard Butler or 1830 under Samuel McCutchon, and were later joined to the house.
