The Greenhouse is one of the jewels of the Ciutadella Park and contributes to reinforce the Ciutadella as a European reference in knowledge, research and innovation. Built 135 years ago by Josep Amargós y Samaranch, it was part of the buildings of the Universal Exhibition of 1888, being a unique building of high heritage and natural value, and a living memory of the history of Barcelona. After a season closed for restoration, the Greenhouse is once again undertaking its main activity: to house specimens from the botanical collection and disseminate knowledge about biodiversity and gardening among the public.
