Signature moment
The monument changes by accumulation
New engineering layers enter the same active lighthouse rather than replacing its identity.
Conceptual illustration only — not to scale.

Cordouan: Continuity Through Transformation
What remains when architecture and technology change around one enduring beacon?
Cordouan preserves one lighthouse identity through architectural layering, optical experimentation, changing power and expanding heritage stewardship.
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
- 1611: A monumental lighthouse enters service — Louis de Foix's tower established a royal monument and an active beacon on the exposed Cordouan plateau.
- 1790: The tower rises without losing its identity — Joseph Teulère raised and remodelled the lighthouse while retaining the earlier monument within the new composition.
- 1823: Fresnel changes how the light speaks — Cordouan received the first rotating lenticular apparatus developed by Augustin Fresnel, making the site a laboratory of lighthouse technology.
- 2021: An active beacon becomes world heritage — UNESCO recognition formalized the global cultural value of a lighthouse that remains in use and continues to require technical adaptation.
Current Status
- Accepted public Heritage Journey.
- Focus lighthouse: LUX-LH-000618.
- Rights-cleared Story media and authoritative source evidence are recorded.
Open Questions
Research still in progress — these do not affect accepted relationships above.
- Confirm the complete custody chain of former Cordouan optics before modeling any museum transfer.
Why LUX?
A present-day lighthouse card cannot show which parts changed and which identity continued.
LUX keeps the structure, signal, place, evidence and uncertainty distinct while making their continuity readable.
