According to historical documents, the villa di Monaciano has been existing since the 18th century, but actually the building we can admire today is the result of a transformation realised between 1870 and 1885.

Alessandro Pucci Sansedoni, a nobleman of Sienese origins living in Florence, who owned the villa at that time, wanted to realise a Romantic park similar to those that were coming into fashion in the Tuscan capital city thanks to architect Giuseppe Poggi and to the Pucci family. It is not by accident that the building departs from the typical Sienese style to be close to the Florentine architecture of the late 19th century.

The wide park surrounding the villa is decorated with fountains and plays of water and is divided into a flower and a Romantic garden, the latter being rich in long-stemmed trees, such as holm-oaks, oaks and horse chestnuts, and featuring also a cedar of the Lebanon.

Apart from an aviary and a lemon-house, in the garden of the villa there is also an uncommon warm greenhouse dating back at least to 1881. In fact, Alessandro Pucci Sansedoni was a passionate botanist as well as a meritorious member of the Regia Società Toscana di Orticoltura (the royal Tuscan society of horticulture). Collections of ferns, orchids, begonias and anthuriums are still cultivated in the said greenhouse.
