Just a bit lower of Washington, a minutes away by train is mythical city of Alexandria. Not the Egyptian Alexandria, but the USA version. Controversial as it is, maybe was named after this great egyptian city to restore the glory and power of new civilisations that came to USA after European religious expells in 16th and 17th century.
An independent city, located along the western bank of the Potomac River, Alexandria is approximately 11 km south of downtown Washington, D.C.
When coming there, already from the train was possible to see The George Washington Masonic National Memorial. This building is called Masonic building (free masonry) and a memorial. It is dedicated to the memory of George Washington, the first President of the United States and a Mason.
As I mentioned, the building is constructed on the memory of fashioned ancient Lighthouse of Alexandria in Egypt.
Alexandria is largely populated by professionals working in the federal civil service so it is nice to take a walk through the hilled streets and enjoy the early 18th century architecture of the family houses.
