Pierre de Gargantua, Prehistoric menhir in Neaufles-Auvergny, France.

Pierre de Gargantua is a sandstone menhir standing in the middle of a field north of Neaufles-Auvergny in the Eure. It measures 4 m high, 2.10 m wide on average and 0.85 m thick, with a girth of 5.36 m at ground level and 4.20 m at human height. Its weathered face, split by a vertical ridge, shows greys, greens and pale yellows.

The stone was first mentioned in written records in 1298 under the name 'longa petra', meaning long stone, and dates back to the Neolithic period. It gained official protected monument status in 1934, securing its preservation for future generations.

Auguste Le Prévost recorded the legend in 1832: Gargantua used the hard sandstone to sharpen his scythe, then threw the stone into the valley. In the 1879 version by the vicomte de Pulligny, the giant mows a field near Neaufles in one stroke with a scythe from Rugles. Local workers long sharpened their tools on the stone.

The stone sits on private property, so visitors should view it from the field's edge rather than trespassing onto the land. Local walking routes pass nearby, making it easy to see the menhir as part of a broader countryside walk.

The name Gargantua comes from local legend claiming that the giant folklore character used the stone for sharpening tools. This playful tradition links the Neolithic monument to the region's storytelling in a way that blurs the line between myth and archaeology.
