The International Hotel was built by architect Paul Martin in 1903, commissioned by Léon Soalhat, who wished to offer his clientele every possible modern convenience available, including central heating for the winter season.
Paul Martin adopted a horseshoe-shaped layout, with a 40m street facade featuring six shops on the ground floor and a belvedere crowning the central pavilion.
Special provisions were made for the era's early motorists, who had access to garages with inspection pits and a dedicated dining room, preceded by washbasins that allowed travellers to "freshen up" before arriving at their table. The hotel also boasted an impressive winter garden, flooded with light thanks to the design of its high conservatory.
The period between 1905 and 1930 saw several development projects that allowed the hotel to reach a capacity of 260 rooms. Used as a military hospital during the First World War, the Hôtel International finally closed its doors in October 1939. Its dismantling began in 1940, with various government departments moving in during the Second World War. The building's sale by lot was scheduled to be completed on 19th February, 1960, with the City purchasing the dining room and garage, which were then converted into exhibition spaces.
