Nineteen competition venues were used for the Olympic Games Antwerp 1920, ten of which remain in use today. Fifteen of the competition venues were existing, two were new and two were temporary. Many of the existing venues were refurbished for the Games. The two temporary venues have been dismantled. Six of the existing venues and one new venue – the Jules Otten Stadium - have been demolished. Though many of the remaining venues have undergone upgrades, only a few still offer high-performance sports facilities.
Built for the occasion, the Olympic Stadium hosted the Opening and Closing Ceremonies and several of the competitions. There was no official Olympic Village. Although most events were held in Antwerp, some competitions took place in other cities; for example football in Brussels and Ghent and sailing in Ostend and Amsterdam.
