The Sky of the Night of the Eiffel Tower Inauguration
On March 31, 1889, Gustave Eiffel climbed the 1,710 steps of his iron tower and planted the French tricolor at the summit, 300 meters above the Champ de Mars. That evening, the tallest structure ever built by human hands pierced the Parisian sky for the first time. This star map captures the starry vault as it unfolded above that audacious metal spire — a firmament that Parisians gazed upon with a mix of astonishment and pride.
Historical context
On March 31, 1889, a fifty-seven-year-old man with a neatly trimmed beard undertook the most symbolic ascent in the history of architecture. Gustave Eiffel, accompanied by a handful of dignitaries and engineers, climbed the 1,710 steps of the tower that bore his name — for the elevator was not yet in service. At each landing, the panorama of Paris widened. At the summit, breathless but radiant, he unfurled an immense French tricolor in the March wind. A cannon fired from the base. France had just planted its banner at the highest point in the world.
Three hundred meters. In 1889, that number was vertigo made real. The Eiffel Tower surpassed the Washington Monument — the previous record holder — by nearly twice its height. It weighed 7,300 tons of puddled iron, assembled with 2.5 million rivets. Eighteen thousand metal parts, engineered to a precision of one-tenth of a millimeter. Two years, two months, and five days of construction. And not a single worker killed on site — an extraordinary feat for the era.
But this engineering marvel was far from unanimously admired. Well before its construction, a petition signed by three hundred artists and intellectuals — among them Guy de Maupassant, Alexandre Dumas fils, and Charles Garnier, the architect of the Opera — was published in the newspaper Le Temps. They denounced this "column of bolted sheet metal," this "odious metal column," this "tragic lamppost," this "metal asparagus." Maupassant, it is said, often lunched at the Tower's restaurant — the only place in Paris, he claimed, from which one could not see it.
The Tower had been built for the 1889 World's Fair, celebrating the centennial of the French Revolution. It was meant to be temporary — dismantled after twenty years. It was saved by its scientific utility: Eiffel installed a weather station, an aerodynamics laboratory, and most importantly, a wireless telegraphy antenna that proved crucial for military communications.
On the evening of March 31, 1889, the sky above Paris offered a spectacle that Gustave Eiffel himself must have contemplated from his vertiginous summit. The late March night was cool and clear. The astronomical spring had just begun, and the transitional sky between winter and spring displayed a particular richness.
To the west, the last glimmers of twilight faded behind the rooftops of Passy. Above, the constellation Orion descended toward the horizon, its belt stars — Alnitak, Alnilam, and Mintaka — tilted like a farewell to winter. Betelgeuse glowed red at the hunter's shoulder, while Rigel, blue-white, marked his foot. Sirius, the brightest star in the night sky, twinkled low on the southwestern horizon, its brilliance amplified by the thickness of atmosphere it traversed.
Higher in the sky, the Gemini twins — Castor and Pollux — shone side by side, two celestial brothers watching over the City of Light. Cancer, subtle, harbored within it the Beehive Cluster, a milky patch visible to the naked eye on a clear night. Leo was rising in the east, Regulus at its head, heralding the spring nights to come. And the Great Bear, faithful companion of navigators and dreamers, culminated nearly at the zenith, its dipper pointing toward Polaris.
The Milky Way stretched across the sky from northwest to southeast, a pale arch of light that Parisians of 1889 could still perceive — light pollution had not yet extinguished the urban firmament. The capital's gas streetlamps cast a soft golden glow, quite different from the harsh white glare of modern LEDs.
Below, on the Champ de Mars, the pavilions of the World's Fair were taking shape. Thousands of workers still labored by lantern light. Forty-nine countries would participate in this celebration of progress. Thomas Edison would present his phonograph. Buffalo Bill would set up his Wild West Show. Thirty-two million visitors would pour through during the exhibition's six months.
But no one gazed at the sky with as much emotion as Gustave Eiffel himself. From the summit platform, at an altitude no human being had reached on a fixed structure, the stars seemed closer. The air was sharper, purer. The murmur of the city rose like a distant hum. Eiffel had arranged a small apartment at the top of his tower — a sitting room, a kitchen, a study — where he would receive illustrious guests, including Thomas Edison himself.
The Eiffel Tower, which its detractors wanted to be ephemeral, became the most visited monument in the world. More than 300 million people have climbed it since 1889. It has been painted 19 times, in shades ranging from Venetian red to ochre yellow, before settling on its characteristic brown. It served as a scientific laboratory, a radio antenna, a symbol of resistance during the Occupation — when the elevator cables were cut to force Hitler to climb on foot, which he refused. It has been the lighthouse of the City of Light, visible from 80 kilometers on a clear day.
That March night in 1889, beneath the stars that watched over Paris, an iron silhouette rose against the firmament for the first time. The metal asparagus had become a miracle. And the stars that shone above it that evening still shine, unchanging, waiting for you to capture their brilliance on your own star map.
