This Grand Logis was enlarged in the 19th century (private residence visible from the street). Its first owner is at the origin of the implantation of the first poplar tree in the Marais Poitevin. The eleven stores on the first floor were used for the storage of goods (wine, wood, fish) in transit to Niort and Marans, then rented until 1960 to farmers who stored their equipment necessary for the exploitation of the marsh.
