The interior, from the vault of the loggia to the little chapel and from the golden hall to the Cristina di Lorena apartment, are decorated with frescoes by Domenico Cresti (known as il Passignano) and Bernardo Poccetti. At the ground floor, you can see the wine cellars and the weapons room. The basement is no more occupied by the Archaeological Museum of Artimino, now located in Piazza San Carlo.
The main characteristic of La Ferdinanda is the sight of the many fireplaces, that’s why it is also called the "Villa dei Cento Camini", or "Villa of a hundred chimneys". Even if they are less than that number, there’s a chimney in every room, all different from one another. Ferdinando I, in fact, during the construction, ordered each room to have a modern heating system of its own to prevent the cold of winter hunting season.
Among the nearby buildings, there's the refined Paggeria, damaged during the war and then restored to host an hotel with its original fireplaces and washbasins.
