New heraldic evidence regarding the Orsini del Balzo princes of Taranto in their capital cities: signs and architecture This study is focused on the analysis of what remains of the references to the Del Balzo-Orsini family which were placed in churches, palaces and fortifications of the cities of Taranto and Lecce, capital cities of the Principality of Taranto. These inscriptions and coats of arms have been partially published in the past without ever being studied in depth and compared from the historical and iconographic point of view. The evi- dences underline an imposing will of self-representation of this emerging family branch together with the families related to it. Even in the short span of a few decades, the members of this family erected absolutely peculiar buildings and urban structures. These familiar “traces”, once connected and contextualized, will contribute to enhance the historical and artistic knowledge recorded in the last decades on the transi- tion age in the fiefdoms of the Kingdom of Naples and in particular on the so-called Orsinian Age.
