Lousonna, Archaeological site in Lausanne, Switzerland.
Lousonna is a Roman settlement in Lausanne with excavated foundations, roads, and numerous building remains near Lake Geneva. The site shows an organized urban layout with residential areas, workshops, and a port area that connected to the lake.
The Roman city grew into a regional center during the 1st century CE and built trade connections across surrounding territories. It eventually declined as Roman power waned in the region during late antiquity.
The objects found here show how Roman building methods mixed with local techniques in the tools and materials used. This place became a meeting point where two worlds intersected in daily life.
The site is reachable by regular buses from Lausanne central station and is located near an adjacent museum with exhibits about the excavations. Guided tours can be arranged in advance to help you understand what you are seeing on the ground.
The port and trade system shows how closely connected this place was to Lake Geneva and how goods moved across the water. This connection to water transport was essential to how the community survived and prospered.
