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.
