[1] An ancient town hall, referred to as La Malmaison, was in existence on the current site, which was occupied amphitheatre in Roman times, in the 13th century.

[2] During the siege of Amiens in summer 1597, the Spanish general, Hernán Tello de Portocarrero, used the partly-built town hall as his headquarters.

[8] The town hall was the venue for the signing, in March 1802, of the Treaty of Amiens which brought a temporary end to the war between France, Spain and the United Kingdom.

[11] In the late 19th century, four statues, representing the aldermen who resisted the Spanish soldiers during siege of Amiens in summer 1597, were installed on a gallery above the ground floor windows.

Another two statues created by the sculptor, Athanase Fossé, were installed on either side of the clock: they depicted the founders of the commune: Bishop Godfrey of Amiens and Louis VI.

[13] Following the liberation of Amiens by troops of the British Second Army on 31 August 1944, during the Second World War, the French tricolour flag was once again hoisted on the flagpole above the town hall.
