The Orto Botanico is yet another gem in the already amazing town of Padova. The garden itself is quite small, but it is notable for its age (founded in 1545) and its contribution to botany and agriculture in Italy. Hundreds of varieties of plants are on display in the circular grounds of the garden in the shadow of the imposing Basilica of St. Anthony, and the entrance fee for students is only 1 euro. Once you've explored the garden, don't miss the Basilica, the impressive Duomo and Baptistry, the truly stunning Cappella degli Scrovegni (with frescoes by Giotto), or any of the other numerous hidden treasures that Padova has to offer.
