The Castle of Luynes has been registered as a historic site since 1926. The construction started in the 13th century, and the building was redesigned in the 15th and 17th century.

A Roman aqueduct which carried water to Tours is visible as a series of piers, some still connected by arches, where it crosses a small valley between Luynes and Fondettes.
