This thirteenth century castle, well preserved, has its origin in the lordship of Senarega and Chiappa, families first mentioned in records of the beginning of the thirteenth century. It became the property of the Fieschi family in 1685 and, then, of the Church of Senarega since 1838. Its construction is dated from the twelfth century, when the square tower was built, and the fourteenth century, when the residential part was set up. The building is connected to the nearby Parish of N.S. Assunta through a stone bridge.

The dungeons are, perhaps, the most interesting and, in some ways, disturbing, part linked to ancient stories and legends: a torture chamber with iron rings affixed to the ceiling and the walls and a trap door where, the legend says, the condemned were thrown.
In the early 80's the Senarega Castle hosted a community for drug addicts, but it is now deserted and closed to the public. Recently it has been acquired on loan, along with the nearby chapel and the surrounding area, by the Park dell'Antola that, in collaboration with the municipality of Valbrevenna, is developing a restoration project for the construction of a facility for walkers and visitors.
