Great Glasshouses and Conservatories Around the World

The grand glasshouses of the world's botanic gardens and parks, inside and out, in the order they were built: from early curvilinear iron palm houses through Victorian and Gilded Age conservatories to geodesic domes, Singapore's cooled giants and a conservatory that opened in 2024. To earn a place, a glasshouse has to be a landmark in its own right and still growing plants today, so you can visit it and walk among what grows inside. Each caption names the garden, when the house went up and what to look for under the glass.
