Botanical Garden (Orto Botanico), Padua

UNESCO World Heritage site inscribed 1997, located in Italy. The world's first botanical garden was created in Padua in 1545. It still preserves its original layout – a circular central plot, symbolizing the world, surrounded by a ring of water. Other elements were added later, some architectural (ornamental entrances and balustrades) and some practical (pumping installations and greenhouses). It continues to serve its original purpose as a centre for scientific research.
