Signature moment
The tower disappears. The warning returns.
Material continuity breaks in 1944; function, place and lighthouse identity are rebuilt in granite.

An exhibition tower becomes an offshore warning
A 57-metre prefabricated metal tower, first assembled for the 1867 Paris Universal Exhibition, was rebuilt on the plateau and lit on 6 August 1869.

The tower is destroyed, but the need for the light remains
German forces destroyed the occupied metal lighthouse in August 1944. Official records reviewed here establish the month, but not 4 August as the exact date for Roches-Douvres.

Reconstruction begins at the edge of possible work
Work began in 1947. Granite was cut and numbered on shore, carried three hours or more to sea, and assembled during short weather windows while workers initially lived aboard the Titan.

Film turns the construction site into social memory
Pierre Gout's Loguivy de la Mer used the real lighthouse works inside a part-fiction, part-documentary story about young fishers financing a cooperative boat.

The granite ship returns the warning to the sea
After seven years and eleven thousand tonnes of transported material, the current lighthouse entered service in 1954 as France's last newly built lighthouse at sea. Official sources conflict between June and the night of 13-14 July for the exact lighting date.

Why it matters
Why this journey matters
Roches-Douvres makes identity continuity visible without pretending that the current building is the tower first lit in 1869.
The story also preserves construction as social memory through archival film while labelling where documentary scenes and staged narrative meet.

Heritage Journey
Roches-Douvres: The Granite Ship
How did a warning survive the destruction of the tower that carried it?
Roches-Douvres preserves a navigational identity across two radically different structures: a metal tower first lit in 1869, destroyed in 1944, and the vast granite-and-concrete lighthouse completed after seven years of post-war work.
LUX Light Archive is the heritage renderer of the LUX143 research field, preserving lighthouse continuity through evidence, memory, movement, and sources.
Understand how this archive fits into the wider research field.
Inside this heritage renderer, Story and Research are two modes of the same evidence-grounded journey: Story gives a guided path, while Research shows the sources, relationships, uncertainty, and open questions behind it.

Identity Changes
- 1869: a prefabricated metal lighthouse begins carrying the Roches-Douvres warning.
- August 1944: the first tower is destroyed; exact day remains unresolved.
- 1947-1954: a new granite-and-concrete structure is built on the same plateau.
- 1954: the replacement restores the light; official sources disagree on the exact June-or-July commissioning date.
- 2000-2017: automation ends keeper residence and historic-monument protection recognizes the post-war structure.
Current Status
- Accepted public Heritage Journey.
- Focus lighthouse: LUX-LH-000255.
- Current white light flashes every five seconds with a published 24-nautical-mile range.
- Rights-cleared hero image and source-linked archival film references are recorded.
Open Questions
Research still in progress — these do not affect accepted relationships above.
- Government sources reviewed here establish destruction in August 1944 but do not confirm the supplied 4 August date for Roches-Douvres; do not publish the exact day without a stronger archival record.Appears in Story: The tower is destroyed, but the need for the light remains
- Secondary and film-catalogue evidence associates the Joliot-Curie family with the first-stone event, but the 1947 construction-start claim and the 1949-1950 catalogue dating are not yet reconciled into one exact ceremony date.Appears in Story: Reconstruction begins at the edge of possible work · Appears in Story: Film turns the construction site into social memory
- DIRM sources conflict: the lighthouse page says the night of 13-14 July 1954, its 2025 guide says 19 June, and POP says June 1954. Keep 1954 certain and the exact date disputed.Appears in Story: The granite ship returns the warning to the sea
Why LUX?
A present-day lighthouse card cannot explain which structure vanished, which one replaced it and what identity continued.
LUX keeps the station, two towers, place, dated relations, source conflicts and licensed media distinct while making one readable story.
