Construction began on the lighthouse in 1730 to assist navigation to Fortress of Louisbourg. It was completed in 1734. A fire in 1736 destroyed the lantern but the stone tower was unharmed and a new lantern was installed in 1738. Lighthouse Point played a decisive role in both the Siege of 1745 and 1758 as, once captured, it provided a commanding gun battery location to bombard the fortress. This lighthouse was badly damaged in 1758 during the Final Siege of Louisbourg and abandoned by the British after they demolished the fortress. Stonework ruins from the first tower are still visible at the site.
The second lighthouse
A square wooden lighthouse with a black stripe was built by the government of Nova Scotia in 1842. The lighthouse was a large -story wooden building supported by a massivemasonrybase. It included the keeper's dwelling in the base of the light. A fog horn building was added in 1902. This lighthouse was destroyed by fire in 1922. The foundation remains visible today and has been excavated and stabilized by Parks Canadaarchaeologists.
