On the building's façade there is a coat of arms which is divided into two: the right depicting a castle with two towers on the sea (identical to another emblem found at the courtyard of the Bitonto Cathedral), and the left depicting a bearded face and a lily. The presence of the initials "O. N." suggests that it belongs to Ottavio de Nicolò or Nicolai, who fought in the Portuguese Restoration War and became vice-admiral of the Marina of Giovinazzo. From the date on the shield, it is understood that the complex was readapted in 1608.
