Inside this garden lies the Buontalenti grotto (1583-1593). Decorated with Mannerist-style scenes from Greek and Roman mythology, the grotto includes copies of Michelangelo's famous Slave series, the originals of which were transferred to the Galleria dell'Accademia . In the 17th Century, the garden was extended as far as the Porta Romana , adding the Vasca d'Isola (pond) at the centre with a fountain and a statue of Neptune. In the late 18th century, Zanobi del Rosso built the Kaffehaus pavilion. Admission: EUR 6 and includes entry to the Museo delle Porcellane, Galleria del Costume , Museo degli Argenti and the Museo e Galleria Mozzi Bardini.
