Last Updated on May 21, 2024 by Darla

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.

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.

Avenches, in Canton Vaud, is a municipality that used to be a Roman Colony called Aventicum. It was, in fact, the capital of the province. Both the Romans and their predecessors, the Helvetians, made Avenches their capital.

The Romans established Aventicum as their capital from 15 to 13 BC. At its peak, it had 20,000 inhabitants. This number has dwindled to less than 500 today.

Nowadays, this charming medieval village is an interesting and attractive town to visit. Many structures in Avenches are listed as Swiss Heritage Sites of National Significance. These include the following:

  • The Roman Ruins of Aventicum
  • Avenches Castle
  • The Cure at Rue du Jura 2
  • The Swiss Reformed Church
  • The Temple à Donatyre
  • The Tour de l’éveque (Bishop’s Tower) with Amphitheater
