Lyndon Baines Johnson Memorial Grove on the Potomac is located on Columbia Island in Washington, D.C. The memorial honors the 36th President of the United States, Lyndon B. Johnson. The grove consists of two parts. The first area, commemorative in nature, is a Texas granite monolith surrounded by a serpentine pattern of walks and trails. The second area is a grass meadow and provides a tranquil refuge for reflection and rejuvenation of the spirit.
