Boston Financial District: Exchange Place
Exchange Place in Boston's Financial District was completed in 1985. It has 40 floors and stands 510 feet high.
A unique feature of this recent building is that the developer retained the State Street facade of the 1891 Boston Stock Exchange building as well as a short piece of the old facade on Congress Street.
I'm not fond of the architecture of this period, but this is an exception. It's zig-zag tower with rounded edges, black gridwork, and dark blue windows make for a dramatic view.
