Look about 150 feet up the Washington Monument and the marble changes shade. The line records a long interruption in construction, changes of quarry and stone that weathered differently.
This animated history traces the story from early promises and dollar donations to Robert Mills’s grand design, an unfinished tower surrounded by cattle, and the engineers who strengthened its foundations from below.
When work resumed in 1880, the replacement marble did not quite match. A narrow Massachusetts band sits between stone from two Maryland quarries. The film follows that visible seam all the way to the aluminum apex placed in December 1884 and the freezing dedication in February 1885.
