For a Zen-like respite from the Piazza dei Miracoli crowd, explore this peaceful walled garden laced with centurion palm trees, flora typical to the Apuane Alps, a fragrant herb garden, vintage greenhouses and 35 orchid species. Showcasing the botanical collection of Pisa University, the garden dates from 1543 and was Europe's first university botanical garden, tended by the illustrious botanist Luca Ghini (1490–1556). The museum, inside Palazzo della Conchiglie, explores the garden's history, with exquisite botanical drawings, catalogues, maquettes etc.
