The Province of Agrigento (whose name was Girgenti until 1927), officially the Free municipal consortium of Agrigento since 2015, is located in the south-west of Sicily and includes 43 municipalities (comuni). The locality name "Agrigento" or "Girgenti", written on the labels of many old sulphur, celestine, gypsum, and aragonite specimens, usually is not referred to the municipal territory of Agrigento (Girgenti), but to a larger territory in many cases identifiable with the province of Agrigento (Girgenti). |
