The remains of a Gallo-Roman temple dedicated to healing and built by a Gallic tribe, the Sulbanectes, in the middle of the 1st century AD. You can admire the ex-votos, coins, vases and fibulae discovered during excavations at the Senlis art and archeology museum. The temple is hidden in the bushes, so you have to follow a forest path to reach it. It is a unique and fascinating site that will take you back in time.
