Lousonna was a Gallo-Roman port during Roman times. The port town was important for commerce with links on Lake Geneva to Roman towns such as the present-day Geneva, Nyon, and Villeneuve.
However, during Roman times, Lausanne was never of political or military importance. Although borders shifted, Lausanne was mostly a backwater at the southern most parts of Germania, ruled from Mainz. Political and military power in the region was concentrated in Avenches and Yverdon-les-Bains.
From the fourth century onwards, Lausanne gradually moved uphill to higher grounds with the Roman port town eventually abandoned. Today, the Roman ruins are some way from the lakeshore, as the level of Lake Geneva was permanently lowered during the nineteenth century. The immediate area is used for various sport facilities and a great area for outdoor activities and strolls along the shores of the lake.
The Musée Romain in Lausanne-Vidy is a fairly small museum on Roman history. The ground floor of the museum, which is built over the foundations of a Roman villa, is used for temporary exhibitions. These exhibitions can cover much more than just the Roman era. As this area is half the museum, the theme and quality of the display very much influence whether the museum is worth visiting at all. Fortunately, the displays are generally excellent and manage to link historic themes well with the present day.
A short walk from the Roman Museum – pass underneath the highway towards the lake – is the Lausanne Roman Archaeological Park. Here many Roman foundations have been uncovered. Visitors can freely explore the archaeological park. Information tables explain the Roman town layout and buildings. The temple was a good 71 m long but the antique port wall is probably the more impressive.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
