Washington Memorial

The Washington monument , made of marble, granite, and bluestone gneiss , is the world's tallest stone structure and the world's tallest obelisk, standing at 169 m. Its construction began in 1848 but not completed until 1884, almost 30 years after architect Robert Mills' death, due to the co-option by the Know Nothing party, a lack of funds, and the American Civil War.

I ask a ranger : why the difference in shading of the marble? visible about 50 m or a quarter up.

The builders ran out of local marble so the materials changed+for years the obelisk remained half-built. When opened in 1888 it became the world's tallest structure, a title previously held by the Cologne Cathedral. The monument held this designation until 1889, when Eiffel's tower completed.

Madeleine, after seeing the Washington Monument: "We came all the way here to see that?"

Me:

Madeleine: "I don't mean it as a bad thing."
