The National Flag Memorial (Spanish, Monumento Nacional a la Bandera) in Rosario, Argentina, is a monumental complex built near the shore of the Paraná River. It was inaugurated on June 20, 1957, the anniversary of the death of Manuel Belgrano, creator of the Argentine flag, who raised it for the first time on an island on the opposite shore of the river on February 27, 1812.
