The Carriage Museum was founded by Bruno Molajoli, director of Gallerie della Campania who, between 1960 and 1979, agreed to house the collection of Marchese Mario d’Alessandro di Civitanova. Further equipage (materials, equipment and carriages) from the collections of Marchese Spennati, Count Dusmet and Count Leonetti di Santo Janni was subsequently added to the main collection.
The stables and coach houses linked to Palazzina Rothschild were chosen as the premises for housing the collection. Both Molajoli and the Marchese di Civitanova wanted to gather evidence for the deeply-rooted Neapolitan tradition of horse racing which was beginning to decline.
The museum, designed by the architect Ezio Bruno De Felice, was opened in 1975 by Raffaello Causa, the new director of the galleries. The new museum layout was presented in 2014 and includes rooms for displaying carriages and gigs and other rooms for the harnesses and accessories.
