Up to 110,000 doses of the Class A drug were found along with the weapon at the grounds of the Cimitero del Verano. The drugs and the gun, believed to have been stolen, were stuffed into a tomb in a wall where the dead are buried. A 42-year-old male marble worker has been arrested on suspicion of drugs charges.
The drugs have since been seized by officers.
The raid came after a car was spotted driving at speed towards the historic cemetery, located near the Basilica of San Lorenzo.
Police were called to the scene and found the drugs stored in the oldest part of the cemetery.
A video was also released showing shocking footage of police detailing where the cocaine was found.
Pulling back a stone wall inside the back of the tomb, two Italian officers show the camera a yellow lunch bag with the drugs meticulously stored inside along with a set of scales and other paraphernalia.
Inside the bright green carrier bag, they reveal a cardboard box with a hand gun inside.
