Hi Vayolene, tops! Thank you.
Makes it the FIRST EVER
Lyon Trade Fair.
The creation of the Foire de Lyon began in 1916 through an initiative by then mayor Édouard Herriot. He decided to build a vast "Palace" to accommodate the commercial stalls that were crowding the quays and streets, and impeding traffic flow in the area. The Fair Palace was built from 1918 to 1938 on land located between the Rhône and Parc de la Tête d'Or. Subsequent construction did not adhere to the original plan. The buildings of the Fair Palace were ultimately destroyed to make room for the Cité Internationale, leaving only the main façade of the central pavilion, now integrated into the Musée d'art contemporain de Lyon. In 1985 the fair was moved to the Eurexpo convention center in the commune of Chassieu, east of the Metropolis of Lyon.
