The castle also housed numerous shops, workshops, laboratories, humble craftsmen and servants homes, the guardhouse, the prison, large cisterns for water (three visible today) and numerous deposits and barns.
The castle was in fact a real city within the city, connected to the village of Arco further down, but at the same time, in case of need, autonomous and self-sufficient.
The beginning of the 18th century marks the decline of the fortress ending with the bombing by French general Vendôme who destroyed many castles in the area.
In 1982 the Municipality of Arco decided to purchase the manor, proceeding with a restoration and protection of the olive grove, making it accessible to the public.
