The origins of Orciano, already documented in the eighth century medieval castle, remains uncertain. The most widely accepted opinion has it that it has arisen as a fee payable to a family of Lombard origin.
It is easy to assume that Orciano has followed the fate of the other villages of the Pisan Hills, Florence fell under the domination with the defeat of Pisa and then adapt to the grand ducal regime. On 14 August 1846 the country was devastated by an earthquake that affected the whole area of the Pisan Hills.
