101 Callahan Dr, Alexandria, VA, United States
Built in the 1920s by the Freemasons, a fraternal organization with members across the world, this memorial honors the nation's first President, George Washington. It is open to the public and admission is free.
Those who are not familiar with Freemasonry may find it a bit mysterious, due to its use of ritual and ceremony. Freemasons themselves, however, make great efforts to dispel rumors of secret societies, instead stressing the Freemason's belief in honesty, morality, and charitable activities, and encouraging those curious about the Order to learn more about it. If you'd like to know more about this centuries-old society, the Memorial is a good place to start; it includes a library and organized tours.
