What was once "the largest room in the world" has been restored
In the early 20th century, rail yards in Washington, DC, the capital of the United States, cluttered the vast expanse west of the US Capitol Building. With the construction of Union Station in 1907, the removal of the rails (and placing them underground) opened up what became, under the McMillan Plan of 1910, the National Mall. But Union Station itself was an architectural masterpiece that has now been restored to its original design.
