During the peak tourist season, from 15 June to 15 September, the City of Antwerp organises the Great Flagging. Throughout this period, City Hall is fully adorned with flags according to the following order and criteria, proceeding from bottom left to top right—first along the Grote Markt side, then along the Suikerrui side:
• The member states of the European Union, in order of their accession dates;
• The countries with a consulate-general established in the City of Antwerp;
• The countries whose honorary consulate is seated within the City of Antwerp;
• The countries whose honorary consulate is seated within the Province of Antwerp;
• The countries whose honorary consulate has jurisdiction over Antwerp;
• The countries whose honorary consulate has jurisdiction over the Flemish Region.
Additionally, the flag of the United Nations is prominently raised at the bottom centre on the Grote Markt side, positioned next to the balcony of the Schoon Verdiep. On the balcony of the first floor, the flags of the districts of Antwerp are also displayed.
