Dansereau House, Historic Second Empire mansion in Thibodaux, United States.
The Dansereau House is a two-story house at 506 St. Philip Street in Thibodaux, Louisiana. Architect Henri Thiberge designed it in the Italianate style with a Second Empire roof. The first floor dates from 1845–47; a second floor was added in 1875 for Dr. Hercules Dansereau.
The building began as a single structure in 1845 for owner James A. Scudday, then received a second story addition in 1875 under Dr. Hercules Dansereau. This two-phase expansion shows how the property adapted to changing needs across three decades.
The house carries two names: Dansereau, for the Canadian family that bought it after the Civil War, and Caldwell Home. Dr. Hercules Dansereau, its owner from that purchase, added the second floor in 1875. Since 2010 it has operated as a bed and breakfast, opened by state representative Damon Baldone.
The property sits on St. Philip Street and operates as a bed and breakfast with modern conveniences for guests. Advance planning is recommended given the historic setting and limited guest capacity.
The house has been listed on the National Register of Historic Places since November 21, 1978. Its later name, the Caldwell Home, is still used alongside Dansereau House, and since 2010 the building has operated as a bed and breakfast.
