# The Light Is Not the Lighthouse

Story ID: `french-lighthouse-identity-evolution`
Language: `en`
Story type: `light_group`

## Narrative Angle

French lighthouse identity is traced through three cases where the signal outlives the material tower, the original optical apparatus, or the keeper regime: La Coubre, Ar-Men, and Cordouan.

- LUX-LH-000251 (lighthouse): Ar-Men Lighthouse /node/937/

## Heritage Assets

- LUX-ASSET-000638: Cordouan lighthouse station fabric (structure)
- LUX-ASSET-000639: La Coubre signal lineage (site)
- LUX-ASSET-000640: Ar-Men lighthouse station fabric (structure)

## Timeline And Relations

- 1611 - historically_part_of - LUX-ASSET-000638 -> LUX-LH-000618: The station fabric carries Cordouan's lighthouse identity across later modifications.
- 1788 - modified - LUX-ASSET-000638 -> LUX-LH-000618: From 1788 to 1790, Joseph Teulère's campaign raised and remodelled Cordouan's station fabric while retaining the lower monument and the continuing lighthouse identity.
- 1830 - historically_part_of - LUX-ASSET-000639 -> LUX-LH-000619: The signal lineage links the successive La Coubre structures to one navigational identity.
- 1881 - historically_part_of - LUX-ASSET-000640 -> LUX-LH-000251: The tower and signal carry the reviewed Ar-Men lighthouse identity.
- 1990 - modified - LUX-ASSET-000640 -> LUX-LH-000251: Electrification and automation changed apparatus and staffing while the signal continued.
- 2019 - restored - LUX-ASSET-000640 -> LUX-LH-000251: Recent works replaced the rotation support and began a broader conservation campaign.
