In Lost, what was the name of the island’s lighthouse station?

In Lost, the island’s lighthouse station was called the Lighthouse.

The Lighthouse is introduced in season 6 when Jacob directs Hurley to take Jack there. Inside, the survivors find a large rotating mirror marked with numbers and locations. Jacob used the lighthouse to observe potential candidates connected to the island from a distance.

Jack’s name appears among the marked locations, which deepens the mystery surrounding his connection to Jacob and the island. The station also becomes important because Hurley follows Jacob’s instructions even though the other survivors do not initially understand the purpose of the place.

The Lighthouse is distinct from the island’s other DHARMA facilities. It is not presented as a DHARMA Initiative station, and its design and purpose are tied to Jacob’s guardianship. The episode “Lighthouse” reveals the station while also exploring Jack’s uncertainty about his role in the island’s larger conflict.
