The first known hominid settlements in the Nice area date back about 400,000 years;[9] the Terra Amata archeological site shows one of the earliest uses of fire, construction of houses, and flint findings dated to around 230,000 years ago.[10] Nice (Nicaea) was probably founded around 350 BC by the Greeks of Massalia (Marseille), and was given the name of Nikaia (Νίκαια) in honour of a victory over the neighbouring Ligurians; Nike (Νίκη) was the Greek goddess of victory. The city soon became one of the busiest trading ports on the Ligurian coast; but it had an important rival in the Roman town of Cemenelum, which continued to exist as a separate city until the time of the Lombard invasions. The ruins of Cemenelum are in Cimiez, now a district of Nice.
