This monument is located near the Tidal Basin and the Jefferson Memorial. The monument and the nice engravings nearby are well worth taking a few minutes to read and reflect upon. Benches to sit on are near.
A hole in the ground in the area may be designed for a fountain, but if so, the fountain or water feature was not operational when I was there.
I highly recommend taking a few minutes to stop by this monument when visiting the nearby Jefferson Memorial.
