Founded in 1924, the Franco-American Historical Museum pays tribute to French support during the American War of Independence and the assistance provided by American volunteers during World War I. It is housed in Blérancourt Castle, whose current appearance dates from its reconstruction between 1924 and 1938, and in a new wing completed in 2017. A pavilion salutes the memory of Anne Morgan, the museum's founder. In the grounds, the "Gardens of the New World" complete the visit.
