I forgot - those poor Romans didn't get to see the precious bankers' architectural carbuncles:

Canary Wharf Group plc is the owner and developer of nearly 100 acres (0.40 km2) of property at Canary Wharf in London. It is notable because over the last 10 years it has constructed more office space in London than any other developer. The group owns 7.9 million square feet of property which is worth £4.9 billion, of which 99% is let (in 2008). (Wikipedia)
