What is "remaisnil"

Remaisnil is a commune in the Somme department in Picardie in northern France. The village contains the Château de Remaisnil, which held two different influential people (one of the Paris subway designers, as evidenced by the tiles used in the wine cellars, which were also used in the Paris metro stations) and Laura Ashley. In the field across from the mansion, remnants of a German V-1 Flying Bomb launch site are visible as well.
