Since Europe Day on May 9, the national flags of the five twin towns of Swindon/Great Britain, Créteil/France, Imatra/Finland, Staryj Oskol/Russia and Gotha/Germany have been flown continuously on this square.

On France's national holiday on July 14, when the French celebrate the storming of the Bastille and thus the trigger of the French Revolution in 1789, a different picture emerged. Framed by the European flags, the national flags of France and Germany flew and in the middle the flags with the city coats of arms of Créteil and Salzgitter. The coat of arms of Créteil, which had not previously been so well known in Salzgitter, attracted particular attention. It shows a silver wave, which stands for the river Marne, a golden cross, which recalls the historical origins as an ecclesiastical feudal lordship, and a golden vine with leaves, the symbolism of which is self-explanatory.

In future, the town twinning square as the gateway to Lebenstedt city center will be flagged with the appropriate flags as a gesture of friendship on public holidays and similarly significant days of the friendly countries and twin towns or when delegations visit. The national flags will fly on all other days. In future, a change of flag will be announced in advance and not explained afterwards, the administration assures.
