Washington Monument is an obelisk on the National Mall in Washington, DC.
The monument, made of marble, granite, and bluestone gneiss is both the world's tallest stone structure and the world's tallest obelisk.
As a landmark of the U.S. capital, the Washington Monument has been featured in film and television depictions.
The symbolic meaning of the shape is referenced in the novel The Lost Symbol by Dan Brown. Fifty American flags (not state flags), one for each state, are now flown 24 hours a day around a large circle centered on the monument.
Forty eight American flags (one for each state then in existence) were flown on wooden flag poles on Washington's birthday since 1920 and later on Independence Day, Memorial Day, and other special occasions until early 1958.
National Cherry Blossom Festival
National Cherry Blossom Festival is a spring celebration in Washington, D.C. Mayor Ozaki donated the trees in an effort to enhance the growing friendship between the United States and Japan and also celebrate the continued close relationship between the two nations.
Today the National Cherry Blossom Festival is coordinated by the National Cherry Blossom Festival, Inc., an umbrella organization consisting of representatives of business, civic, and governmental organizations. More than 700,000 people visit Washington each year to admire the blossoming cherry trees that herald the beginning of spring in the nation's capital.
