Step 1 : Introduction to the question "Where is the world's oldest botanical garden?"

... The Garden of Padua was founded upon deliberation of the Senate of the Venetian Republic. It was devoted to the growth of medicinal plants, the so-called "simple plants" (Orto dei semplici - simples were herbs that were used as they are rather than in admixtures) which produced natural remedies, and also to help students distinguish genuine medicinal plants from false ones. A circular wall enclosure was built to protect the garden from the frequent night thefts which occurred in spite of severe penalties (fines, prison, exile). The Botanical Garden was steadily enriched with plants from all over the world, particularly from the countries that participated in trade with Venice. Consequently, Padua had a leading role in the introduction and study of many exotic plants, and a herbarium, a library and many laboratories were gradually added to its Botanical Garden.
