The Tarbert Lighthouse (also known as Tarbert Island Lighthouse) is an active lighthouse in the north of County Kerry, Ireland. The tower serves as a harbour light to guide ships safely through the Shannon Estuary. The tower has been in operation since March 31, 1834. A striking cast-iron bridge connects the lighthouse to the island's mainland, making it accessible at any tide. The lighthouse is an iconic landmark for travelers taking the Shannon Ferry between Tarbert (Kerry) and Killimer (Clare).
