Nemi is a town and comune in the Metropolitan City of Rome, in the Alban Hills overlooking Lake Nemi, a volcanic crater lake. It is 6 kilometres northwest of Velletri and about 30 kilometres southeast of Rome.
The town's name derives from the Latin nemus, or "holy wood". In antiquity the area had no town, but the grove was the site of one of the most famous of Roman cults and temples: the Temple of Diana Nemorensis, a study of which served as the seed for Sir James Frazer's seminal 1890 work on the anthropology of religion, The Golden Bough.
In 1514 Marcantonio I Colonna gave to Nemi the "Statuti e Capituli del Castello di Nemi", the first city statute with rules and regulations to observe.
