Paper focuses on the 18^th-century project by the architect Giovanni Maria Galli Bibiena the Younger (1694-1777) for the Sansevero Palace in Naples. Giovanni Maria, second-born son of the famous set designer Ferdinando Galli Bibiena, worked in the Kingdom of Naples since 1743 as set designer, architect and professor of architecture during the Charles and Ferdinand IV of Bourbon eras.  Unpublished documents have helped to discover the Neapolitan works of Giovanni Maria and his important clients in the city, such as the Pignatelli family and the Prince of Sansevero, Raimondo di Sangro. In particular, he was «Architetto della Casa» Sansevero for several years and supervisor of the restyling project of the palace in San Domenico Maggiore Square since 1760. The Sansevero Palace, built in the early years of the 16^th century by the architect Giovanni Merliano from Nola, was radically remade by Bibiena since the second half of the 18^th century. Thanks to the study of important documentary sources it has been possible to recreate the original project, based on restyling stables, garages, atrium, grand staircase and the Prince apartment.
