La Branche Plantation Dependency House, on the River Road in St. Rose, LA, is an interesting stop on the Southeastern Louisiana Plantation tour, because it is a visit to a plantation home that no longer exists. All that remains is the Dependency House, which had a function that is pretty much what the name implies. It is what we usually call a Garconniere (French for bachelor quarters). La Branche is now listed on the National Register of Historic Places.
The Zweig family, of Germany, built the plantation in 1792. Because of neglect, the effects of the Civil War, the economics during and after Reconstruction, and the division of the property among heirs, there is little left to indicate what was once there, save for "an alley" of Oaks. The site of the main house is on private land, and is not accessible to anyone, without the permission of the owners. The Dependency House is on land currently owned by the Lentini family, and is open to the public.
