The Colline district of Livorno takes its name from the old Porta alle Colline, the Livorno customs gate which stood where Via Gramsci finishes today, near the hospital. Until the early 1900s this gateway was known in Livorno as the Porta ai Sughi because it was here, against the walls built by the Lorraines, that the local farms used to deposit their manure to be used later during the sowing season.
