The first funicular railway in Le Tréport was inaugurated on July 1, 1908, in the presence of Gaston d'Orléans and his wife Isabelle, Count and Countess of Eu. Thanks to its popularity, more than 2,000 travelers purchased their round-trip tickets in the first month of operation. This amazing idea was born after the extension of the Eu-Le Tréport electric tram line to serve the "Les Terrasses" district proved impossible due to the significant elevation difference on Rue de la Commune de Paris.
