Associazione Calcio Robur Siena 1904, commonly referred to as Siena, is an Italian football club based in Siena, Tuscany. The club was re-incorporated in 2020 after the bankruptcy of the previous legal entity Robur Siena, which itself was the reincarnation of the original club Associazione Calcio Siena S.p.A.. A.C. Siena's predecessor was founded in 1904. Siena plays its home games at the Stadio Artemio Franchi. The ground's capacity is 15,373 and is located in the centre of Siena. History Formed in 1904 as Società Studio e Divertimento (Society for Study and Entertainment), as a sports club characterised by a black and white striped jersey which was derived from the city of Siena coat of arms.
