In 1911 the International Exposition of Industry and Labour took place in Turin to celebrate the fiftieth anniversary of the Italian National Unity. The first part of the film, "Nei cantieri dell'Esposizione", shows an unusual view of the river Po with the construction sites of the pavilions. The construction sites are also visited by the then Prime Minister Luigi Luzzatti. The second part of the video presents "La giornata d'esultanza", or the celebrations for the inauguration on April 29, 1911, in the presence of royalties of Italy.
