Stairs Exchanging Places

From Dave Brigham:

Does something look amiss? What's an old, red-carpeted, marble staircase with fancy balusters doing in a sleek, modern building in Boston's Financial District?

This is 53 State Street, also known as Exchange Place. Built between 1981 and 1985, this 40-floor skyscraper incorporates part of the facade of its predecessor, the Boston Stock Exchange, which was completed in 1891. As part of an agreement with preservationists, the developers eventually agreed to also include the stock exchange's former staircase in the main lobby.

For more about this building and the staircase, see this Atlas Obscura article. For more about using old facades on new buildings -- the practice is called façadism -- see April 6, 2019, "UPDATE: Cashing Out (And Learning About Facadism)."
