Alexandre Mouton House, Greek Revival house at Lafayette Street, Louisiana.

The Alexandre Mouton House at 1122 Lafayette Street in Lafayette has a two-story main house with an attic and cupola, and wooden porches on both floors. An Acadian house linked by a covered wooden porch and a brick smokehouse stand on the same property. The first two buildings have cypress siding and briquette entre poteaux construction.

The original building began around 1800 as a simple one-room house with a kitchen built by Jean Mouton. It later grew into the residence of Louisiana's eleventh governor and gained prominence because of this connection.

The house is also called the Lafayette Museum, and its French name is Maison d'Alexandre Mouton. It was the home of Alexandre Mouton, the 11th governor of Louisiana and the state's first Democratic governor, and it is linked to other historic families of the Attakapas country.

The house stands at 1122 Lafayette Street in Lafayette, Louisiana, and is also known as the Lafayette Museum. The National Register listing covers three contributing buildings on the property: the main house, the Acadian house linked to it by a covered wooden porch, and the brick smokehouse. Visitors should confirm current opening arrangements with the museum before travelling.

The property's three contributing buildings were listed together on the National Register on June 18, 1975. The main house and the Acadian house linked by a covered wooden porch both use cypress siding and briquette entre poteaux construction, while the third is a brick smoke house.
