Brussels is especially complex. It is the only place in Belgium where French- and Dutch-speaking communities live together, and is governed by a maze of political institutions. It has a parliament and government; 19 autonomous borough assemblies; six different police zones; and 33 public housing companies. Together, the Brussels region — with a population of just over 1 million — has 166 ministers, mayors and city councilors. That’s more than Berlin and Paris combined.
