Giardino Torrigiani, Private botanical garden in Oltrarno district, Florence, Italy

Giardino Torrigiani is a private ten-hectare English-style park inside Florence's historic centre, entered from via de' Serragli 144-146 and via del Campuccio. Its south-west edge runs along the old city walls by viale Francesco Petrarca. Paths link the Casino Torrigiani al Campuccio, the Merlin grotto, an amphitheatre, the Gymnasium, the Romitorio, the Ossuary and Gaetano Baccani's 22-metre neo-Gothic Torrino, built in 1824 on an artificial hill.

The Torrigiani bought land here from 1531; the casino on via del Campuccio rose shortly after 1571. In 1798 Pietro Guadagni inherited through his uncle Cardinal Ludovico Maria Torrigiani and took the name. Between 1802 and 1817 he expanded to about ten hectares up to the walls and Piazza Tasso. Luigi de Cambray Digny designed the romantic park from 1813, succeeded in 1819 by Gaetano Baccani, who built the 22-metre neo-Gothic torrino in 1824.

The garden's paths follow an Arcadian and Masonic programme devised for Marquis Pietro Torrigiani, a Freemason; a visitor's guide was printed in 1824 to explain it. Gaetano Baccani's 22-metre Torrino, built in 1824, has three levels alluding to the three degrees of Masonic initiation. At the via de' Serragli entrance a statue of Osiris, god of agriculture, holds tablets listing the rules for entering.

The garden is private: entry is from via de' Serragli 144-146 or via del Campuccio 49-51-53-55, and visits must be arranged in advance, not made freely. The gate on via de' Serragli is marked by a statue of Osiris holding tablets with the rules for entering. Allow time to walk the roughly ten hectares, which border the Medici walls along viale Francesco Petrarca.

The garden's 1824 visitor guide listed over thirty points of interest, among them an underground hypogeum, Merlin's Grotto, an interior carousel, a lemon house and a stream crossed by a bridge. A marble column honours botanist Pier Antonio Micheli, who rented land here in 1716 to acclimatise newly introduced plants.
