The hall is the argument
France has been building rooms for crowds since 1855, and the rooms outlast the fairs booked into them. Aeroplanes were first shown to the Paris public in 1909 under the glass vault of the Grand Palais; the show left for Le Bourget in 1953 and never came back indoors.

- 03The SalonsThe recurring fairs — their founding years, their grounds and the logic that kept them running.
- 04On the StandsNamed objects shown to the French public for the first time — the cars, aircraft and machines that made the salons worth attending.
- 05Who Built ThemThe engineers, architects and organising bodies behind the structures — Eiffel, Dutert, Contamin, Girault and the committees that commissioned them.

The Salon Where a Cow Is Always the PosterThe Salon International de l'Agriculture brings the farmyard to the Porte de Versailles each February — live animals, champion judging and all.340 wordsAdmissions to the Exposition Universelle of 1900 — the highest recorded at any exposition until Osaka in 1970, and the reason the Grand Palais, the Petit Palais and the Pont Alexandre III were built to last.
