The Rio de Janeiro Botanical Garden or Jardim Botânico is located at the Jardim Botânico district in the South Zone of Rio de Janeiro.
The Botanical Garden shows the diversity of Brazilian and foreign flora. There are around 6,500 species (some endangered) distributed throughout an area of 54 hectares (130 acres) as well as numerous greenhouses. The garden also houses monuments of historical, artistic, and archaeological significance. There is an important research center, which includes the most complete library in the country specialising in botany with over 32,000 volumes.
It was founded in 1808 by King John VI of Portugal. Originally intended for the acclimatisation of spices like nutmeg, pepper and cinnamon imported from the West Indies, the garden was opened to the public in 1822, and is now open during daylight hours every day except 25 December and 1 January.
