Rosignano Solvay
An early name for the town was "Paese Novo" (New Country in Italian). In 1917 the city changed name to Rosignano Solvay, where the name "Solvay" originates from the name of a big chemical factory from Belgium, the Solvay Group, which in 1914 built many buildings for treating and making chemicals, such as: Sodium hydroxide, Sodium bicarbonate and Sodium carbonate.
