The Old Lower Lighthouse (1716 – 1906): One of Portland’s original lighthouses, this structure was built to help mariners navigate the hazardous coastline. After being decommissioned in 1906, it found a new purpose as a bird observatory and field centre, attracting nature enthusiasts who study the island’s rich birdlife.

The Old Higher Lighthouse (1716 – 1906): Situated further inland, this lighthouse worked alongside its lower counterpart to mark the island’s southernmost point. The Old Higher Lighthouse was the first official lighthouse on Portland Bill, though a beacon had existed on the site as early as 1620. Initially, it was illuminated by sixteen oil burners, named after their inventor, Argand, a Frenchman. Notably, it was the first lighthouse to use Argand lamps and the first in the world to feature a true reflector.
