Ancient Badolato, due to its characteristics, can be considered entirely as a historic centre; however, for descriptive convenience, it can be divided into macro-zones, with the most prominent being Corso Umberto I.
It was initially named Via Maggiore but was changed to Corso Umberto I upon the death of the king from the House of Savoy. Starting from the side of the Church of San Domenico, near the water reservoir of the 1920 water supply system, it ends at the medieval gate called ‘e Japacu, developing along the ridge of the hill sloping towards the east.
Within its one-kilometer length, one encounters numerous palaces belonging to noble bourgeois families: Menniti, Nisticò, Militerna, Aponte, Gallelli, Bressi, Paparo, Sgrò, Caporale, Guarna, and more.
The most frequented part of Corso Umberto I is its central, narrowest, and flattest section, located between the Main Church and the open space near the Church of the Annunziata. Within this stretch, there are some premises housing public services such as the Town Hall and the Pharmacy.
