Back in its heyday, the trading floor in UBS' Stamford office, once the largest in the world and big enough to hold 23 basketball courts, was a symbol of everything that went right on Wall Street. Packed with traders, it was a non-stop cacophony of screaming, constant motion and furious energy - to an outsider sheer chaos, which somehow ended up generating millions in profits for the bank every day. Some time around 2008, just before the financial crisis hit, it looked like this.

Fast forward 8 years later, when all that's left of the UBS trading floor, and the legacy of that version of Wall Street, is this.
