Each of the Fades Viaduct's great piers has a base larger than a tennis court. That fact tends to land differently once you learn the piers are made entirely of quarried granite, rise over 92 meters from the floor of the Sioule river gorge, and remain the tallest bridge piers ever built in traditional masonry. When the viaduct opened on October 10, 1909, after eight years of construction in the rugged Auvergne highlands of central France, it was the tallest bridge in the world -- not just among railway bridges, but across all categories. More than a century later, its granite columns still carry the landscape's weight with a kind of monumental calm.

From a distance, the viaduct's proportions can be difficult to grasp. The piers do not look like bridge supports so much as free-standing towers, each one a structure that would be impressive in isolation. Their granite surfaces have weathered to the grey-brown of the surrounding...

The early 20th century was the twilight of monumental masonry construction. Steel and reinforced concrete were already transforming bridge engineering, and the Fades Viaduct belongs to the last generation of structures that relied on the sheer mass and compressive strength of cut...
