The last stage in a tour of the Museum, the Sacristy houses two nineteenth-century funerary monuments still dedicated to members of the di Sangro family. Adorning the walls are various marbles dating back to the seventeenth-century decorations of the Sansevero Chapel, as well as large slabs of the eighteenth-century labyrinth flooring.
Since 2005 this room has also been home to a painting by Giuseppe Pesce, the Madonna and Child, a painting using coloured wax made by Raimondo di Sangro.
The Sacristy currently also houses the Museum’s bookshop, renovated in 2017 with functional furnishings. The design is inspired by the motif of the labyrinthine floor of the Sansevero Chapel and was the work of Francesco Celebrano. It was commissioned by Raimondo di Sangro in the second half of the eighteenth century.
