Port Hercule Contre-Jetée de l’Avant Port Light

The Port Hercule Contre-Jetée de l'Avant Port Light is a small beacon positioned at the entrance of Port Hercule in Monaco. It flashes green signals to help vessels navigate safely into the deep-water harbor.

The beacon was installed in 2006 as part of a modernization of the harbor's navigation systems. The site has served as a natural anchorage since ancient times when Greek and Roman traders used these waters.

The light contributes to Monaco's long connection with the sea and the working harbor that sustains the port's daily activities. Passing boats and fishing vessels make use of this aid while anchoring in one of the Mediterranean's busier harbors.

The best views of this light are from the public paths around the harbor, especially in the evening when its green flashes are most visible. The harbor is easily accessible on foot from the town center and has several viewing spots along the waterfront.

The beacon sits alongside a patented water wall technology in the harbor's breakwater system, an engineering solution rarely seen elsewhere on the Mediterranean coast. This design allows the harbor to work with natural water movement while protecting moored vessels more effectively.
