L’église Saint-Denis

It dates back to the 14th century. As far back as the 7th century, Tillenay had a chapel of Saint-Denis near the site of the present church, which was completely altered around 1830.

Inside, a number of items listed as Historic Monuments bear witness to the church's long history, including an 18th-century limestone stoup and a 15th-century limestone statue of a saint with a book.
