The current name of the gate derives from the Italian version of the original name Johannis Bonorum hominum, who was certainly a character who had been responsible for its restoration or who lived nearby, as has been seen several times relating to other gates.
Here an acccess way was created in the north-west of the old walls - on the opposite corner to Porta Japasseri - which also marked the entrance into the city of the Via Numicia.
Its first construction dates back to the Middle Ages, although it was probably restored in Gothic style around the 14th century. At this time the city built a second wall with new gates replacing older ones, with the exception of both Porta Bonomini and Porta Japasseri, which were located in parts of the walls which were still in use.
Located at the top of a steep slope, the gate retains only its stone piers and dates back to the last of its many reconstructions from around 1708, just after the terrible earthquake of two years previously.
