The Botanical Garden was instituted in 1966 in the locality of Pian della Fioba. Situated in a rocky area, some 900 metres a.s.l., it is traversed by a footpath that winds through its various sections, and hosts spontaneous species of the Apuane Alps, typical of calcareous peaks, siliceous peaks and wetlands. Worthy of note are an experimental arboretum of conifers, a wetland for hygrophilous species, a vaccinium grove with bilberries and associated species, and a chestnut cultivar.

Dedicated to physician and botanist Pietro Pellegrini from Mass, the Garden has been the object of study by Italian and foreign researchers, and venue of numerous conferences. It has been open to the public since 1981 and is managed by the Commune of Massa in collaboration with the three Universities of Tuscany, whose representatives sit on the technical-scientific committee.
