Thomas Jefferson Memorial, Washington

Designed by John Russell Pope, this Roman-style monument to Thomas Jefferson, the nation's third president and author of the Declaration of Independence, is elegant and simple. Jefferson's 19-foot statue stands within, surrounded by some of his most inspirational writings. This is a perfect after-dinner destination. At night, the view of the Washington Monument across the tidal basin is one of the most attractive in Washington, especially when the cherry blossoms are in bloom.
