Palazzo Lanfranchi, designed and produced by brother Francesco Cupertino, commissioned by Bishop Vincenzo Lanfranchi, It was built between 1668 and the 1672 to fulfill the function of diocesan Seminar; It constitutes the first major signal of an urban development since the end of the seventeenth century began to project beyond the Sassi. In 1864 It was expropriated and destined to receive the grammar school, dove, between 1882 and the 1884, Giovanni Pascoli taught. It currently houses the National Museum of Medieval and Modern Art of Basilicata. The architectural development organically incorporated the pre-existing church of the Carmine. A string-course cornice divides the facade into two parts: in the upper part there are pilasters with capitals and 9 ornamental arches, the largest of which holds a window-rosette; in the lower as well as some pilasters, There are 5 allocated statues in as many niches: from left are represented San Nicola, the Madonna del Carmine on top of the portal, San Filippo Blacks, St. Hyacinth and St. Bartholomew. These last two opens a window, on top of which you can find the coat of arms of Bishop Lanfranchi. On the top of the facade, in an asymmetric position, It is placed a gable with clock. A staircase leads us inside and overlooking the seventeenth-century cloister. Along the walls of the courtyard are busts representing the principal architects of the realization of this building, in particular the three bishops that have taken place during the period of conception and definition of the structure: Lanfranchi, the Ryos Culminarez and Brancaccio, in addition to the bust of Count Malvezzi Malvinni that contributed economically.
