The power, influence, and contribution of Ancient Rome to modern history are legendary. Due to the proximity of Switzerland to Rome, it comes as no surprise that the Ancient Romans looked to expand to present-day Switzerland.
Was Switzerland part of the Roman Empire? Yes, Switzerland was part of the Roman Empire. In fact, it was even part of its predecessor – the Roman Republic.
In 58 BC, Julius Caesar won against the Helvetii tribe during the Gallic Wars. The Romans started settling in Switzerland one battle after another. This win paved the way for the Romans to rule parts of Switzerland.
Swiss Cities and Municipalities Under Roman Empire
During the next two centuries of peace after the Gallic Wars, lots of cities developed. These cities prospered under Pax Romana. These Roman cities were:
- Aventicum (Avenches)
- Lusonna (Lausanne)
- Noviodunum (Nyon)
- Genava (Geneva)
- Octodunum (Martigny)
- Sedunum (Sion)
- Vindonissa (Windisch)
- Augusta Raurica (Kaiseraugst)
- Arbor Felix (Arbon)
- Tasgaetium (Stein am Rhein)
- Salodurum (Solothurn)
All these Ancient Roman settlements are still wonderful to visit these days. The Romans helped build castles, streets, waterworks, thermal baths, and forums.
Historical Monuments from the Roman Empire in Switzerland
Thanks to the Roman Empire, Switzerland has these wonderful historical monuments and infrastructure. There are three Roman settlements in Switzerland that have excavated and preserved structures and remains from the Roman period. These are present-day Avenches (Aventicum), Kaiseraugst (Augusta Raurica), and Windisch (Vindonissa).
Some other cities, like Nyon and Chur, also have vestiges of the Roman Empire that you could visit.
In this article, we list the tourist destinations brought about by the Roman Empire.
