What happened here?
Bell Rock Lighthouse first exhibited its light in 1811. The Northern Lighthouse Board identifies Robert Stevenson as its engineer. Its offshore reef setting is central to understanding the navigation problem the tower addressed.
How to read this scene
- A tower surrounded by sea suggests a different purpose from a church or inland watchtower.
- Study the relationship between the landing place, reef and passing vessels.
- Do not use the lighthouse's present-day equipment as evidence for its first year of operation.
Which date does the question mean?
The milestone is the first exhibition of the light, not the beginning of construction or a later modernization.
