History of Wolf Rock Lighthouse in Timeline

Wolf Rock Lighthouse stands on a treacherous rock 18 nautical miles east of the Isles of Scilly and 8 nautical miles southwest of Land's End, Cornwall. Its remote and exposed location made construction extremely challenging. The lighthouse warns ships of the submerged hazard, protecting them from the dangerous rock. The name "Wolf Rock" comes from the howling sound produced by gales rushing through the rock's fissures.

1904: Installation of a more powerful light-source and a reed fog signal

In 1904, a Matthews incandescent oil burner replaced the Douglass multi-wick oil burner. A reed fog signal was also installed, which sounded a four-second blast every 30 seconds using compressed air produced by a small steam engine with a coke and coal-fired boiler.

1906: Change in light characteristic and decommissioning of the bell

In 1906, the light characteristic was changed so that the flash (red or white, alternating as before) was displayed every fifteen seconds rather than every thirty. The bell was decommissioned.
