The Shiny Gem Warehouse

The Palermo Warehouse was the Barzini's diamond warehouse, where illegal goods were shipped around after passing through the Barzini Hub in Mid Town. Ruled over by Simon Fletcher and Victor Barzini, it was heavily guarded and hidden to the east of France, away from the prying eyes of the police.

The warehouse began to lose trade in 2011, as well as to come under attack from the police following the death of Sergio Turrera and Bobby Toro, which was pinned on the Barzinis. Fletcher eventually knuckled under pressure from the Corleone family, who bought him out and eliminated the Barzinis.
