Just like in the bordering quarters, streets and squares of Salario are mostly named after Italian cities (south of Villa Albani) and rivers (in the northern area). Odonyms of the quartiere can be categorized as follows:
Salario is among the first 15 quartieri born in 1911 and officially established in 1921.
In 1926 it was reduced following the establishment of the Quarter Q. XVII Savoia (currently Trieste).
The territory immediately outside Porta Pia remained a rural area until the end of the 19th century, like all the areas outside the Aurelian walls then known as "suburbia".
The area, crossed by Via Nomentana and Via Salaria, which originate from there, hosted hunting lodges and country residences since the 18th century, such as Villa Albani – still existing today and whose park occupies a good quarter of the territory – and Villa Patrizi (in the quarter Nomentano). The latter stood immediately outside Porta Pia and was sacrificed to the needs of urban expansion of Rome after the unification of Italy. The site is now occupied by the Ministry of Transport.
The first building activities on the new allotments outside the Aurelian walls began outside Porta Pia and Porta Salaria as early as the last two decades of the 19th century.
However, it was only in 1911 that the city administration sanctioned the birth of the new quarters, making them official in 1921.
The area of the quarter Salario was included within the territory defined by Porta Pia and Porta Salaria up to the bridge over the Aniene and the left bank of the same river.
This territorial delimitation was then revised in 1926 with the establishment of the quarter Savoia (the current quarter Trieste), which included all the areas beyond the current Viale Regina Margherita, thus reducing in a relevant way the area of the quarter Salario.
