The new glass Orangery at Prague Castle, completed between 1999 and 2001, combines the historic function of the 16th-century site with a cutting-edge architectural design reflecting the 20th-century's technological advancements. Initiated by Olga Havlová, wife of President Václav Havel, the project aimed to revive the tradition of cultivating tropical plants while introducing an elegant and functional structure to the Royal Garden.

Spanning nearly 100 meters, the Orangery is designed as a semi-circular shell formed by a diagonal stainless steel mesh, glazed with toughened laminated glass. The mesh is stabilized by glass and metal cross walls and supported at the rear by a triangular truss, efficiently transferring horizontal and vertical forces. This innovative design creates column-free interior spaces, divided into three zones with distinct climatic conditions to support germination, growth, and vegetation. Automated roller blinds provide shade during summer and insulation in winter, ensuring optimal conditions for the plants.

The light and transparent structure harmonizes with its historic surroundings while offering a modern interpretation of the site's original function. The building's stainless steel and glass construction gives it a sense of weightlessness, enhancing its aesthetic appeal and blending seamlessly with the Royal Garden.
