At the height of the June Pisano the Ancient Walls are dressed in new colours: these are those of the flowers and small shrubs that grow high up in the spaces between the stones and whose roots contribute to the stability of the monument. To learn more about this particular urban flora, on Saturday 11 June the Walls of Pisa and the Botanical Garden are organising a special guided tour: starting from the Piezometric Tower of the Fibonacci Pole (access from Via San Francesco or Via Vittorio Veneto), a walk at altitude up to Piazza dei Miracoli and finally a stop in the Botanical Garden in Via Roma, a true jewel of the city that contains plant species and stories to tell. The staff of the Botanical Garden and Museum will illustrate to participants both the characteristics of the vegetation they will encounter along the route on the top of the Walls, and the particular beauties of the open-air museum that houses plants from all continents.
