Marigot, Saint Martin: Submarine Cable Landing Point

Marigot is the capital of the French Collectivity of Saint Martin, located in the northeastern Caribbean. As a coastal settlement, it serves as one of three submarine cable landing points on the island, and is home to one international submarine cable connection. That cable, the Global Caribbean Network (GCN), links Marigot into a regional arc spanning several Caribbean territories and extending to the United States mainland, enabling both inter-island and transatlantic-adjacent connectivity.

The GCN system connects Marigot to Guadeloupe, Saint Barthélemy, the United States, and the Virgin Islands (U.S.), tracing a corridor through the northeastern Caribbean island chain. This positions Marigot as a node in a wider regional network that bridges French Caribbean territories with anglophone islands and North American endpoints.

Cables Landing at Marigot, Saint Martin

The Global Caribbean Network (GCN) is the sole submarine cable landing at Marigot. Measuring 890 kilometres in length, the system reached ready-for-service (RFS) status in 2006. Beyond Marigot, the GCN connects to Guadeloupe, Saint Barthélemy, the United States, and the Virgin Islands (U.S.), forming a multi-country Caribbean loop with a North American terminus. The cable provides Marigot with direct submarine links to both neighbouring French territories and broader regional hubs.

Regional Context

Saint Martin hosts three submarine cable landing points in total: Marigot, Baie Longue, and St. Louis, each served by a single cable. Marigot's cable count places it on equal footing with its two island peers in terms of the number of systems served. Together, these three landing points distribute submarine cable infrastructure across different coastal sections of the island.

Network Role

Marigot functions as a single-cable terminus within the Caribbean submarine cable graph. Through the GCN, it maintains direct connectivity to Guadeloupe and Saint Barthélemy within the French Caribbean, as well as to the Virgin Islands (U.S.) and the United States, spanning an 890-kilometre system commissioned in 2006. This means Marigot's connectivity profile is focused rather than diversified, relying on one cable to serve its international bandwidth pathways.

As the capital of the French Collectivity of Saint Martin, Marigot's role as a landing point ties the island's principal administrative centre into a network that connects French, American, and British Caribbean territories along a single cable route. Within the regional submarine cable graph, this makes Marigot a distinct point of entry for the island's French administrative zone, complementing rather than duplicating the connectivity provided by Saint Martin's other two landing points.
