The Constitution Gardens were dedicated in May 1976 as part of the United States Bicentennial and were declared a living legacy to the US Constitution by President Ronald Reagan in September 1986. During World War I, the US government built temporary offices on this site. Those buildings remained until the early 1970s when President Nixon ordered their removal and replacement by a park. On a small island in the middle of the lake lies a memorial to the 56 signers of the Declaration of Independence, dedicated in 1984.
