Where can you see 400 inventions for 2023 under one roof? My first stop at the Foire de Paris, the Lépine Competition (Concours Lépine, Pavillon 1 Porte de Versailles). The results of the competition will be announced on the evening of May 7.The Lépine competition has been active for 122 years. Foire de Paris is a giant home show plus! https://www.foiredeparis.fr
