Hercules Port is a natural bay at the foot of the ancestral rock of the princes of Monaco.
It is one of the few, if not the only deep-water port of the French Riviera.

The new sea wall also makes it possible to welcome major cruise ships (up to 300 metres in length). More than 206 cruises have been scheduled for 2008 and 245 for 2009.

This new outer port made it possible to create an additional dock for hosting some twenty yachts from 35 to 60 metres and two of 100 metres opposite the new yacht club, a resolutely modern building designed by Sir N. Foster, on which construction work has begun. This has brought the total capacity of Hercules Port to 700 berths.
