The current remains are those of the 15th-century gate and its barbican or artillery boulevard. The earliest remains on the site date back to the 1st century, with the remains of an ancient domus, a street, and its wooden gutter. The first Guillaume Gate was built around 1185; a wall can still be seen a little further along Rue de la Porte Guillaume. Source: https://journals.openedition.org/cem/14214?lang=en

Easy and very beautiful hike following the river and pond; however, be careful at the roundabout on the way back to Lucé.

Using the power of moving water to drive a mill wheel is an ancient invention that dates back to pre-Christian times. Thanks to such a construction, human or animal muscle power could be easily replaced by a watercourse - natural or artificially created - in order to grind grain into corn, for example. There are essentially two different ways of driving watermills: either the water simply hits the blades of the water wheel from below to set it in motion; or the water is guided above the wheel and falls onto the blades; this type of construction is more efficient due to natural gravity.
