The Hypothesis

The 1889 grounds reused standing palaces and an existing rail-served district, with the Eiffel Tower's 'construction' photos showing a strangely clean site and the 1878 Trocadéro already in place.

Paris 1889 gives us the cleanest-looking construction photos of any fair: a bare field under a rising tower, with the earlier Trocadéro already standing through the arch. The vast Galerie des Machines was reused once and then pulled down in 1910.

What the photos and records show

  • Durandelle's 23 November 1888 photo shows a bare, levelled field under the tower piers, with no ground cranes or material stockpiles in view.
  • The finished 1878 Trocadéro stands across the river in the same frame.
  • A rail yard and train line run right beside the grounds in the view from the tower.
  • The record gives the Galerie des Machines a span of about 115 m; it was reused in 1900 and demolished in 1910.
  • The Beaux-Arts palace shows tile ornament, stone-look piers and a raised terrace.

Open questions

  • Where was the material yard for the tower and the Galerie?
  • Why demolish a 115 m span in 1910 after reusing it once?
  • Which palace surfaces were plaster and which were fired tile or stone?

What would settle it

  • Site photos of the storage and assembly yards for the tower iron.
  • Demolition records for the Galerie listing recovered materials.
  • Pre-1878 plans of the Champ de Mars and Trocadéro hill.

  1. 1No work campA bare field under the towerDurandelle's photo of 23 November 1888 shows the ground under the rising tower as a bare, levelled field. No ground cranes or large stockpiles of iron are visible around the piers.The questionWhere were the material yard and workforce for a tower of this size?
  2. 2Repeated motifThe Trocadéro already standing through the archFramed in the tower's arch, the finished Trocadéro palace from 1878 stands across the river with its two towers.The questionHow many of these 'temporary' fair palaces were left standing for the next fair, and what was there before 1878?

  1. 1ScaleThe Galerie des Machines at true scaleThe aerial view shows the Galerie des Machines and the domed palaces as huge blocks across the Champ de Mars, with a balloon in the sky. The record gives the Galerie a span of about 115 m.The questionHow was a span that size raised for a single season?

  1. 1Impossible timelineA moving gallery over a vast iron spanInside the Galerie, a raised travelling gallery rides above a vast iron span. The record says the hall was reused in 1900 and demolished in 1910.The questionWhy build a hall this strong only to take it down two decades later?

  1. 1Masonry, not plasterTile and stone on the Beaux-Arts palaceThe Palais des Beaux-Arts shows ceramic or tile ornament, stone-look piers, statues and a raised terrace with stairs.The questionWhich of these surfaces are plaster and which are fired tile or stone, and has anyone ever tested a fragment?
  2. 2Below-grade windowsA raised terrace at the baseThe palace sits on a raised terrace reached by stairs, so the ground floor stands above the walkway.The questionWas the terrace built up for the fair, or was the surrounding ground lowered?

Hypotheses this fair feeds

Patterns where this fair, its buildings or its photo clues are part of the evidence.

Strong110 entriesThe ground came up: buried floors are everywhereBuried ground floors, stairs that go down to a door, raised streets and dug-out temples appear in 35 countries in our collection, from Seattle to Rome to Edfu. Common sense says ground doesn't rise metres in a few centuries without something bringing it. The documented causes vary (river silt, drifting sand, volcanic ash, rubble, deliberate street raising), but the result is the same: older cities sit under newer ones far more often than most people picture. The open possibility is that some of the raising on record was the cleanup of a deposit rather than a choice.
