The BBC website has an interesting article about the significance of different European cities in the history of the EU:

Nowadays, things have become more difficult. Since EU leaders decided to hold all their summit meetings in Brussels, the scope for naming treaties and processes after cities has narrowed.

But then, for Eurosceptics, the word "Brussels" itself requires no further explanation.

There may be no "Brussels process" or "Brussels strategy", but the Belgian capital does appear in common phrases such as "Brussels rules against merger" or "Brussels cracks down on bent bananas", where the city is simply used as a pejorative (and not very helpful) term for any of the EU's institutions.
