In addition to exhibits on science and technology, the exposition included a retrospective on Walloon art and an amusement park.
A military maneuver ground north of town became the residential area of Droixhe.
The exposition also served as an incentive to complete flood control work around Liège that had been delayed by the First World War.
The exhibition resulted in a modest fiscal loss for the organisers and the city.
Vestiges of the exposition included a new airport and train station, control of the Meuse, the commencement of the Albert Canal and the Pont de Coronmeuse, as well as reconstruction of places damaged during the war.
