The harbour is also known as Carrick Roads and is one of the largest natural harbours in the world. HistoryThe lighthouse was designed by James Walker and built in 1835 by Olver of Falmouth, for Trinity House and the original light came from eight Argand oil lamps mounted on a revolving frame. The light was seen to flash once every twenty seconds.[2] Later an additional lamp and reflector were installed 'in the living room of the principal keeper' which shone a fixed light through a square window in the direction of a dangerous cluster of rocks known as The Manacles.[3] (At the time the principal keeper and his family lived in the tower itself, while the assistant lived in the cottage, linked to the lighthouse by a covered way). A fog-bell was installed in 1865,[4] replaced in 1882 by a larger, two-ton bell, {{convert|5|ft|m|sing=on}} in diameter (reputedly the heaviest bell in Cornwall).[5]It hung from a girder attached to the front of the gallery.[6] A set of weights, descending a {{convert|38|ft|m|sing=on}} shaft, drove the rotating optic; during foggy weather additional, heavier weights were engaged and the same mechanism then also activated the bell, which sounded four times every minute.[4] Later, the light source was changed to pressure vapour. A large (first-order) fixed optic was introduced along with a clockwork occulting mechanism; the size of the lens meant that the height of the lantern had to be increased.[4] An electric light was introduced when electricity was connected to the lighthouse in 1954. Today the light is automated, flashing every 15 seconds, with a red sector for The Manacles and a range of 22 miles. The fog horn blasts once every 30 seconds.[7] When the fog bell which hung from the gallery at the front of the tower, was dismantled in 1954, it was donated to a local church, but after many years of sitting on the church front lawn, was taken away to be melted down. St. Anthony's lighthouse was featured in the intro of the UK version of Jim Henson's Fraggle Rock, as "The Fraggle Rock Lighthouse". Nearby St. Mawes is also featured in some scenes from the programme. See also{{stack|{{Portal|Cornwall|Lighthouses}}}}
