Cellere is located in the heart of the Lazio region on a tuff rock outcrop. The name may derive from Ceres, the goddess of Messi, to emphasize the richness of the place. According to other scholars the name comes from the Etruscan ‘cells’ or ‘cave’ or ‘pantry’ because the place was the granary of Vulci and some wells have been found for storage of agricultural products.
The first documents of its existence date back to an a purchase and sale contract of 738 DC. The anti-pope Innocent III granted the castles of Canino and Cellere to Viterbo.
In 1254 it passed to the nearby Toscanella (Toscania today) and in the fourteenth century was given to the Farnese family. Pope Paul III included it in the Duchy of Castro, created in 1537 for his son Pier Luigi and it went through a period of splendour.
When Castro was destroyed in 1649, Cellere returned to the Holy See. In 1788 Pius VI granted the lease to the marquis Casali Patriarch.
