- Interiors have been adapted according to the needs, the culture and the tastes of the times. The actual look dates back to the nineteenth-century renovation, when the large stone staircase with beautiful iron railings was made and the organization of the rooms setted. Details such as doors and decorations, largely due to Lodovico Gamberucci of Radicofani, favorite artist of the Volterra aristocracy of the time, are from this era. Brunellesco Dello Sbarba, new owner since 1910, revisited the palace to the changing habits and needs of the family, expanding it, providing it with running water and heating, improving toilettes and beautifying some rooms with new wall paintings by the local painter Menotti Caluri.
- In the eighteenth century, the main staircase, narrowest of the actual, was where now is the kitchen , and leds directly to the large entrance hall. The stair access to the floors of Ricciarelli Palace and the contiguous Contugi Palace, but there were secondary and secret stairs. The noble floor was dedicated to sociality, and the main apartment, lived by the main branch of the family. The kitchen was on the second floor of the Contugi palace, while on the second floor of the Ricciarelli palace there was a large room dedicated to the unmarried women; other apartments were destined to children, cadets, and servitude. The mezzanine and cellars was used as food storage, while other flats were inhabited by steward and sub-stewards, with rooms used for writing, functions which they maintained until the mid-900.
In the nineteenth century, the representation apartment was built on the first floor, accessible through the new stair of honor. The apartment was composed by a ballroom, a billiard room, various lounges, bedrooms study rooms and a chapel.
On the second floor a large dining room, lounges, kitchens and servants apartments, bedrooms and private apartments were located in the lateral sides of the first and second floor.
At the end of the 19th century the Ricciarelli, and later in the twentieth century, Brunellesco Dello Sbarba, made rentable apartments.
