Ten historic glasshouses and glazed pavilions: two distinct Kew buildings, Copenhagen Palm House, Liverpool Sefton Park Palm House, Laeken Royal Greenhouses, Schönbrunn, Adelaide, San Francisco Conservatory of Flowers, Madrid Retiro Crystal Palace and Berlin Great Tropical House. This is an architectural selection, not an age or size ranking. The Madrid pavilion later became an exhibition space, and several buildings have been restored. Photographs do not establish present visitor access. Authors, source pages and open licenses are listed below.
