In 1800, the palace, once seat of the bailiff, became the property of the Romanazzi-Carducci family and took on the characteristics of a noble palace.
After almost a century of splendor and decorum, Prince Guglielmo, in 1967 donated the palace and all its furnishings and valuables, to the municipality of Putignano, to transform it into a museum, today identified as a civic museum, more commonly, as the museum of the prince .
The main facade, which always overlooks the square Piazza Plebiscito, is the result of the renovation of the nineteenth century; the side one, has an eighteenth-century body above which opens a terrace with a hanging garden.
From the main entrance, one enters the atrium of the building, characterized by a double loggia façade that leads through a short staircase to the first noble floor, consisting of a series of harmonious rooms with architectural lines, richly decorated and furnished with precious furniture, paintings, books, porcelain tapestries, silverware and glassworks. A large part of the artistic heritage is of Neapolitan origin, which flowed following successive marriages. The most prestigious objects, probably acquired through the marriage with the Princess of Saluzzo of Corigliano, are the paintings made up of masterpieces of various origins and datable between the XVI and the XX century, ascribable to various pictorial schools. We also report a very rich collection of minor arts, created by the most important Italian and French craftsmen between the 1800s and the 1900s, among which table clocks stand out.
Among the many collections, the richest is the collection of weapons.
The heart of the noble floor is the "Yellow Room", once a privileged place for social life, used for conversation and "romantic" dance nights.
The vault still preserves the frescoes, the furniture is composed of four Turkish-style sofas arranged in the corners, a sofa and a gilded console table with a Neapolitan-made velvet top; the walls are embellished with golden yellow damask tapestries also used as curtains on interior doors and windows that blend well with the gilded wooden mirror. The palace still retains part of the Prince's shoe collection and in one of the bathrooms, prints and beauty products.
