Hidden beneath the surface of Lake Geneva, a major engineering project is underway.
A new fibre optic cable is being laid between Geneva and Villeneuve to boost capacity as demand for data continues to soar.
Underwater robots are preparing the lakebed before divers install the cable, working 40 metres down with just 15 minutes on the bottom.
Backed by telecom operators and public authorities, the more than CHF 10m project is expected to be in service by October.
