About the location (from Wiki):
The European Central Bank (ECB) is the institution of the European Union (EU) which administers the monetary policy of the 17 EU Eurozone member states. It is thus one of the world’s most important central banks. The bank was established by the Treaty of Amsterdam in 1998, and is headquartered in Frankfurt, Germany. The current President of the ECB is Jean-Claude Trichet, former president of the Banque de France. The bank is based in Frankfurt, the largest financial centre in the Eurozone. Its location in the city is fixed by the Amsterdam Treaty along with other major institutions. In the city, the bank currently occupies Frankfurt’s Eurotower until its purpose-built headquarters are built.
