A free book backs UNESCO push for the Eiffel Tower

Thierry Rayer has published a free bilingual book on the Eiffel Tower with scientific input from Françoise Combes and an introductory note by Philippe Coupérie-Eiffel. The project is tied to a campaign to win separate UNESCO World Heritage recognition for the monument, highlighting its scientific history and cultural significance.

Why it matters: - The Eiffel Tower campaign is trying to move the monument from a shared UNESCO listing to an individual inscription under its own name. - Supporters say the book strengthens that case by framing the tower as both an engineering achievement and a scientific tool that shaped research, communications and public memory. - The project also spotlights the lack of women among the 72 names engraved on the monument and links heritage recognition to a broader debate about scientific memory.

What happened: - Thierry Rayer published La Tour Eiffel, monument universel des sciences with scientific contribution from Françoise Combes and an avant-propos by Philippe Coupérie-Eiffel. - The book is available free online in French and English. - The publication is meant to support the mobilization for individual UNESCO recognition of the Eiffel Tower. - The book is published by the Cercle d'Études Scientifiques Pierre Rayer in the Universæ Analysis collection.

The details: - The Eiffel Tower has been part of UNESCO’s “Paris, rives de la Seine” World Heritage listing since 1991. - The committee backing the initiative wants separate recognition for the tower because of its architecture, scientific role, international influence and symbolic power. - The book traces how the tower was used to study wind, support aviation progress and develop telecommunications. - It also revisits the tower’s role in altitude weather observations, air-resistance tests and wireless telegraphy. - The publication says time signals sent from the tower connected astronomy, navigation and telecommunications. - Rayer’s research uses an interdisciplinary method called Universæ Analysis to study the tower’s axes, symmetries, proportions and structural organization. - The analysis compares the tower’s silhouette with a recomposition involving the Sphinx of Gizeh, the stela of Thutmose IV and the Luxor obelisk. - The author presents those comparisons as geometric and historical interpretation rather than settled fact. - Philippe Coupérie-Eiffel wrote that the research fits a duty of transmission and deepening knowledge of Gustave Eiffel’s work. - Carelle Moukémaha handled general and editorial coordination and also contributed to the book. - The book is aimed at readers, teachers, researchers, heritage professionals and media outlets. - The French edition carries ISBN 978-2-489407-02-0. - The digital French and English editions are free of charge. - More information is available in the author's LinkedIn profile.

Between the lines: - The campaign is building a heritage argument around science, not just aesthetics or engineering. - By pairing UNESCO advocacy with a free bilingual publication, the committee is trying to widen the audience beyond specialists and policymakers. - Combes’ contribution adds institutional scientific credibility, while the women-in-science section broadens the cultural message.

What's next: - The committee is calling on institutions, media and the public internationally to support the bid. - The book is intended to feed the case for a distinct World Heritage inscription for the Eiffel Tower. - The longer-term goal is to secure recognition of the tower as a unique work of human ingenuity and a vessel of scientific knowledge for future generations.
