Built in the second half of the nineteenth century by engineer Greco for the Testasecca family, it incorporated, as was customary at the time, several pre-existing buildings, unifying them and giving the structure an elegant façade that would bring prestige both to the city and to the family that owned it.
Like other palaces in the city, the façade is two-toned, alternating white with the ochre color of the Sabucina stone. However, unlike other buildings where white serves as the background for darker decorative elements, in Palazzo Testasecca the ochre forms the base, while the columns, capitals, pilasters, and balustrades in white stone stand out prominently.
