The City of Frankfurt was the scene of a 25.000 strong anti-austerity demonstration on Wednesday, March 18, the day of the inauguration and grand opening gala of European Central Bank's (ECB). The new skyscraper attracted crowds of protestors from all over Germany. As the protest took off the crowds moved into the stornghold of many German and international banks. The construction of the new ECB premises in the East End of the city had cost approximately 1.3 billion EURO. The demonstrations were called by the broad "Blockupy" alliance which included many left groups, social movements, trade unionists and a host of other individuals. The organisers loaded two special trains and over 60 coaches from 39 European cities with protestors for the demonstration.
