The most interesting thing for me is that is a representation of $160,000,000 outgoing a year for Google and presumably even more in (assuming the average employee makes $80k/year and that there are 2,000 people working at that building).
This street is Barrow Street in the docklands area of Dublin. They've only just recently purchased the building opposite this HQ which goes by by the name of The Montevetro Bulding. Goole are set to rename it...wait for it...Google Docks.
