The history of Segovia is rooted in deep antiquity. Initially, a fortified Celtic settlement existed in this territory; however, Segovia began to take shape as a proper city after the Roman conquest of Spain, around 80 BC. The first written mentions of the city appear in the works of the Roman historian Titus Livius in the context of the Sertorian War, where the settlement is described as a strategically important point.
The development of the city was predetermined by a unique combination of natural and geopolitical conditions:
- Geography and Defence: The city was founded on a high rocky promontory, washed by the rivers Eresma and Clamores. This location turned Segovia into a natural fortress that was easy to defend.
- Transport Routes: Segovia was situated at the intersection of important Roman roads connecting the north and the centre of the Iberian Peninsula, which facilitated the development of trade.
- Political Power: In the Middle Ages, the city acquired a special status, becoming one of the favourite residences of the monarchs of Castile, which ensured an influx of investment and an architectural flourishing.
From the earliest stages of its existence, the city demonstrated a high level of engineering culture. The main proof of this is the famous Roman Aqueduct, built in the 1st–2nd centuries AD without the use of binding mortar — a masterpiece that provided residents with water and symbolized the power of the empire.
Economically, Segovia's early prosperity was based on agriculture and livestock farming. Later, the city became a vital centre for cloth production and the wool trade, which allowed for the formation of a wealthy class of citizens and the construction of numerous Romanesque churches that have survived to this day.
