Point Lookout Lighthouse

The Lighthouse is a location in Point Lookout.

A Meeting of the Minds
The last main quest in the Point Lookout (add-on) takes place in the Underground Lab (basement) of the lighthouse. Before the Great War, the lab was known as the St. Aubin Medical Facility. Sometime after, Professor Calvert began using it as a secret laboratory. It is the location of the final confrontation between Desmond Lockheart, Calvert, and the PC.

There is an unmarked quest in which the player can turn on the lighthouse. The note to start this quest is found at the top of the Lighthouse and outside of Haley's Hardware, to the right of the front entrance.
