Santena (pron. sàntena; in Piedmontese Santna) is a comune (municipality) in the Province of Turin in the Italian region Piedmont, located about 15 kilometres (9 mi) southeast of Turin on the right bank of the Po.
The frazione of Gamenario is known for the Battle of Gamenario, fought on 22 April 1345 between the Guelphs and Ghibellines. Sights include the castle, built by Carlo Ottavio Benso in 1712–20. It houses furnitures and memories of the families who lived there, including a vase donated by Napoleon III of France to Camillo Benso, Conte di Cavour in 1856. Nearby is a 23-hectare (57-acre) English landscape garden built under Cavour's father, Michele Benso, in the early 18th century.
