The history of Salamanca is rooted in deep antiquity, dating back to the Iron Age. The first settlement emerged on the hill of San Vicente, overlooking the Tormes River, approximately 2,700 years ago. The city was founded by Celtic tribes (Vettones or Vaccaei) and originally bore the name Helmantica.
In written sources, the city first makes a bold appearance in 217 BC, when it was besieged and captured by the famous Carthaginian general Hannibal. Subsequently, under Roman rule, the settlement transformed into an important city of the province of Lusitania, receiving the name Salmantica.
The transformation of a small Celtic hillfort into a thriving ancient polis was driven by several strategic factors:
- Geographical location: Its position on the hills provided natural protection, while proximity to the Tormes River offered access to water and fertile lands.
- The Silver Way (Vía de la Plata): Salamanca became a key node on the most important Roman highway connecting the south (Mérida) and north (Astorga) of the Iberian Peninsula. This guaranteed a constant influx of merchants and travellers.
- The Roman Bridge: The construction of a monumental stone bridge across the river in the 1st century AD (part of which has survived to this day) made the city an indispensable crossing for military and trade purposes.
Even in the early stages of its development, Salamanca demonstrated traits that defined its future:
- Exchange economy: Thanks to its status as a transport hub, the city became a centre for the trade of livestock and agricultural produce, which laid the foundation for its wealth.
- Cultural synthesis: Local Celtic traditions gradually blended with Roman civilisation. Civic infrastructure developed actively in the city, forums and temples were built, contributing to the rapid Romanisation of the population.
