Alexandria’s most prominent landmark features a fine view from its 333ft tower, where you can see the Capitol, Mount Vernon and the Potomac River. It is modeled after Egypt’s Lighthouse of Alexandria, and honors the first president (who was initiated into the shadowy Masons in Fredericksburg in 1752 and later became Worshipful Master of Alexandria Lodge No 22).
To visit the tower, you must take a 60-minute guided tour (general admission only gets you into the 1st- and 2nd-floor exhibits). Tours depart at 9:30am, 11am, 1pm, 2:30pm and 4pm.
