Galway, Ireland

Galway, Ireland: Submarine Cable Landing Point

Galway is a city in County Galway, situated on the west coast of Ireland between Lough Corrib and Galway Bay. As Ireland's most populous settlement in the province of Connacht, it occupies a prominent position on the Atlantic-facing edge of the island. One submarine cable currently lands at Galway, connecting Ireland northward across the North Atlantic to Iceland and establishing a direct high-capacity link between the two island nations.

The single cable landing at Galway is the IRIS system, which runs a northerly corridor between Ireland and Iceland. This route is intercontinental in character, spanning open Atlantic waters to bridge two distinct national networks. The IRIS cable gives Galway a role in the broader European submarine cable geography by extending connectivity toward the North Atlantic, a corridor that relatively few submarine cable systems serve directly.

Cables Landing at Galway, Ireland

IRIS is a submarine cable system with a length of 1,770 km, reaching its ready-for-service status in 2023 on a draft basis. The cable connects Galway, Ireland with Iceland, running beneath the North Atlantic along a route that links two island nations separated by a significant expanse of open ocean. IRIS represents a direct submarine link between the Irish and Icelandic national networks, providing a discrete connection path between Western Europe and the North Atlantic island of Iceland.

Regional Context

Within Ireland's submarine cable network, Galway joins a set of fourteen landing points distributed across the country, which together host sixteen cables in total. Dublin leads among Irish landing points with three cables, while Kilmore Quay hosts two. Galway, along with Ballinesker, Ballygrangans, Castlefreke, and Clonshaugh, is among the single-cable landing points that contribute to Ireland's distributed coastal cable infrastructure. With one cable, Galway ranks within the top 86 percent of Irish landing points by cable count.

Network Role

Galway functions as a single-cable terminus rather than a multi-cable hub, with its network role defined entirely by the IRIS connection to Iceland. This positions the city as Ireland's western gateway for the Iceland corridor, offering a direct path across the North Atlantic that does not route through the country's busier eastern or southeastern landing points. The IRIS cable at Galway is one of a relatively small number of submarine systems worldwide dedicated to the Iceland route, making Galway a distinct node in the European segment of the North Atlantic submarine cable graph.
