Great Exhibition at the Crystal Palace
Prince Albert and Henry Cole organized the first international exhibition of industry and manufactured goods, housed in Joseph Paxton's cast-iron and glass Crystal Palace. Over six million visitors attended in six months, and the fair became the model for the world's fair as a national showcase of industrial power. It set the template later fairs followed: a purpose-built exhibition hall, national pavilions, and displays meant to demonstrate a country's technical and imperial standing.
