the seat, since it was already functioning as much of the administration was already working there in offices space loaned from the Belgian government. During this time Belgium, Germany, the Netherlands, and the European institutions themselves favoured Brussels; Luxembourg City wanted to maintain the seat of the ECSC (or be generously compensated); France supported Strasbourg, and Italy continued to promote Milan. However, it was decided that the Common Assembly, which became the Parliament, should instead be based in Strasbourg—the Council of Europe (CoE) was already based there, in the House of Europe. The chamber of the CoE's Parliamentary Assembly could also serve the Common Assembly, and they did so until 1999, when a new complex of buildings was built across the river from the Palace. Provisional agreement The creation in 1957 of the European Economic Community (EEC) and the European Atomic Energy Community (EAEC or Euratom) created new duplicate institutions to the ECSC (except for the Parliamentary Assembly and Court of Justice, which were shared). On 7 January 1958, it was decided that Brussels, Luxembourg City, and Strasbourg would again be provisional venues until a final decision. Strasbourg would retain the Assembly, Luxembourg City the Court and both Brussels and Luxembourg City would host meetings of the Councils and Commissions (or High Authority). The discretion of the exact meeting place of the new Councils was given to the President of the Council. In practice, this was to be in the Château of Val-Duchesse until the autumn of 1958, at which point it would move to 2 Rue Ravensteinstraat in Brussels. Meanwhile, the ECSC Council was still based in Luxembourg City, holding its meetings in the Cercle Municipal on Place d’Armes. Its secretariat moved within the city on numerous occasions, but between 1955 and 1967, it was housed in the Verlorenkost district. On 21 June 1958, the Parliamentary Assembly recommended to the Council that the Assembly should have its seat in the same place where the other organisations are based, although it accepted that plenary sessions could be held elsewhere. The Assembly also nominated three cities to be the seat of the institutions (Brussels, Strasbourg and Milan), however no permanent agreement was reached. The provisional arrangement was reiterated on 8 April 1965 with the "Decision on the provisional location of certain institutions and departments of the Communities". This was following the Merger Treaty, which combined the executives of the three Communities
