Sanzeno (German outdated Sanzinnen) is a small community with 923 inhabitants (as of December 31, 2015) in the Italian province of Trentino. It is located about 24 km southwest of Bolzano, near the Lago di Santa Giustina. Archaeological finds prove that the place was already inhabited at the time of the Räter. The Fritzens-Sanzeno culture has its name from him. For some time there is an archaeological museum (Museo Retico) in the village. In 397 AD, Christian martyrs Sisinius, Martyrius and Alexander, of Cappadocia, were killed in the area. After Sisinius the parish church is named. Even the village itself takes its name from the saint, as the dialectal San Sesen became Sanzeno. Away from the inhabited center is located in the municipality of Coredo the Sanctuary of St. Romedius (Italian: San Romedio).
