Savigliano (Savijan in Piemontese) is a comune of Piedmont, northern Italy, in the Province of Cuneo, about 50 kilometres (31 mi) south of Turin by rail. It has important ironworks, foundries, locomotive works (once owned by Fiat Ferroviaria, now by Alstom) and silk manufactures, as well as sugar factories, printing works and cocoon-raising establishments. It retains some traces of its ancient walls, demolished in 1707, and has a fine collegiate church (S. Andrea, in its present form comparatively modern), and a triumphal arch erected in honour of the marriage of Charles Emmanuel I with Infanta Catherine of Austrian Spain.
