This paper deals with the residences of public authority across Europe from the emergence of the state system to the present. It is concerned with the addresses, the buildings, their surroundings and the symbolic significance from the point of view of builders and the public. The building styles have been heavily influenced by the examples of imperial and papal Rome, and a dominant model of a European capital city building has evolved. There are also some systematic differences, particularly for those countries with a dramatic history of constitutional change and for those with a decentralized process of state-building in the early stages of the process. In the second half of the 19th century, and probably again currently, the residences of public authority should be read in conjunction with the positioning of a series of civic institutions. The display of state authority has been increasingly accompanied by the representation of national identity. More recently, however, a touch of cosmopolitanism has been added in many capitals. The reading of these capitals is therefore now more ambiguous. This will probably intensify under the impact of the emerging European multilevel governance system. At the same time, this governance system has become increasingly based in Brussels. For this city to symbolically represent Europe is a very difficult ambition in the context of its multiple capital roles. However, Brussels has a long history of dealing successfully with such urban challenges in spite of major conflicts and drawbacks.
