As evidenced by the remains of mosaics and potsherds discovered in the mid-19th century, the church at Lageyrat was most likely built on the site of a Gallo-Roman villa, from which the area undoubtedly derives its name (Lageyrat or Lageyrac, the suffix -ac meaning "estate" in Gallo-Roman times). The church, dedicated to the protomartyr Etienne, was probably founded very early, perhaps as early as the Merovingian period. Although some parts of the building, such as the nave and entrance door, may date from the 11th century, it is now mainly Gothic in appearance, thanks to the 15th-century reconstruction of the choir, transept and square bell tower surmounting the transept cross. The latter parts are vaulted, but only the north arm of the transept has retained its original vaulting.
