The patron saint of Antey-Saint-André is Saint Andrew the Apostle, celebrated on 30 November. The parish church dedicated to him appears to have been built near the remains of a 1364 medieval fortified house: only a tower is thought to survive from the earlier building, incorporated in 1555 into today's bell tower structure, whose belfry, pierced with pointed-arch mullioned windows, is now topped by an octagonal spire; the interior has a rectangular plan with three naves. On the municipal coat of arms, Saint Andrew's cross recalls the local parish's patron, while the golden lion on a red and black field is a variant of the regional emblem and the fir trees recall the territory's vast woodland heritage.
In medieval times the undisputed protagonist of local history was the house of Challant, here represented by the branch of the lords of Cly, descending from Bosone III, who appears in an investiture act of 1212, and from Bosone IV, considered the family's founder: his two sons, Bonifacio and Goffredo, granted franchises to the subjects of Torgnon and Antey in 1293 and 1304 respectively.
