A Giant Greenhouse That Changed Architecture

Built in 1851, the Crystal Palace was a massive glass and iron marvel that proved buildings could be mass-produced like machines. It was three times the size of St Paul's Cathedral but was assembled in just five months.

Before this structure arrived, most grand buildings relied on thick stone or brick walls. Architect Joseph Paxton, originally a gardener, broke the mold by using prefabricated iron parts and glass panels that allowed light to flood the entire space. It felt less like a building and more like a cathedral of light. This project set the stage for the modern era of skyscrapers and modular construction techniques used globally today.
