Thoroughbred auction sales are an integral part of Deauville's identity. Indeed, they have been held there since 20 August 1887, on which date 20 horses were offered for sale. This initiative was the project of Gustave Lyon, whose father-in-law created the sales complex named « Chéri » where the first sales were held. In 1892, Lyon bought the plot of land between avenue Hocquart de Turtot and rue du Coteau (now named rue Florian de Kergorlay) at the same spot where the current Elie de Brignac sales complex, now owned by ARQANA, is situated today. In the spring of 1968, the Agence Française de Vente de Pur Sang was formed with a focus on the sale of yearlings. Philippe Augier and Elie de Brignac team up in 1977, injecting a wave of professionalism, giving birth to a period of euphoric growth without precedent. At the same time, their competitors Office du Pur Sang, based at Saint-Cloud and absorbed by Goffs France in 1979, also has its hour of glory thanks to the Arc sale.
