The Alderney Lighthouse was constructed from granite in 1912 under the guidance of local businessman William Baron.

It was electrified in 1976, and automated in 1997, when the last resident lighthouse keeper left.

The Trinity House Central Planning Unit in Essex controls and maintains the lighthouse.

It still functions as a lighthouse, but is open for guided tours during the summer months[4] when it is linked with the rest of the island by the Alderney Railway.
