Parco Chigi

In regards to the complex of the palace and the park, some well-known architects contributed, such as Gian Lorenzo Bernini and Carlo Fontana.

[3] The park is particularly important within the regional park of the Castelli Romani: in fact, it is one of the few green areas of the Colli Albani in which there has been no penetration of chestnut trees, but the oldest plant species have survived, mostly oaks.

The wooded area that now makes up the park was known as nemus Aricinum during the Roman era, and was dedicated to the goddess Diana.

[4] After the advent of Christianity, the sacred nature of the forest was lost, and it eventually became a hunting reserve during the Renaissance owned by the Savelli family.

Other notable features of the park include the Uccelliera, an aviary built in the 17th century,[3] and the Vignola, a small building originally used as a vineyard.
