The date above the door

Text: an original contemporary lighthouse-history-report-style practice extract.

The visitor board above the lighthouse door gave 1894 as the date of construction. It looked definite, but the board carried no source. When I asked the attendant where the date came from, she brought out a guidebook printed in 1972. Its sentence said only that the tower was "believed to have been completed in 1894".

That wording sent me to the old logbook. An engineer's note from 1896 described "the recently altered lantern room", but did not say when the original tower had been built. A newspaper cutting in the same folder placed the opening ceremony in 1897, although its writer admitted that the ceremony followed repairs. None of these sources directly proves or disproves 1894. The certainty had grown as a cautious phrase was shortened, then fixed onto a board visitors read as fact.

The next board should keep 1894 only as "a possible date", followed by a short note naming the guidebook and explaining the later evidence. Some visitors may find that less satisfying than a single year, and the note will not discover the missing date. It would, however, let them see the difference between a source repeating a claim and evidence that actually establishes it. A history display should make uncertainty visible rather than hide it behind a clean line of paint.

The writer tries to show that a definite-looking historical statement can hide uncertainty in the evidence. Evaluate how successfully this is achieved, and whether the writer's recommended wording for the next board is justified. Support your views with detailed reference to the extract.
