Cobblestones Again: Europe

Several weeks ago, my blog about Seattle cobblestones generated a bit of interest so I thought I would follow up by discussing a few old cobblestone roads from Europe. I am using the term cobble a bit loosely, as technically it refers to a stone ranging in size between 64 and 256 millimeters. Furthermore, cobbles typically are rounded due to ice or water. In this context, a cobble is a stone used as a paving material.

My favorite are the gray cobbles used throughout Rome. Locals call the three-inch-square paving blocks, “San Pietrini,” little Saint Peters, playing on St. Peter’s role as the rock of Christianity. In his landmark De Architectura, or The Ten Books of Architecture, Vitruvius referred to the lava that made the stones as hard, enduring rock, calling it siliceae, or silex.

More exotic cobbles are found in Seravezza, one of the great localities for marble in Italy. It was here around 1519 that Michelangelo went in search of white marble for the façade he had designed for the church of San Lorenzo in Florence. The church was never built but Michelangelo did open up quarries still used at present. In the sidewalks of Seravezza, you can find a wide variety of the many colors of marble quarried in the Apuan Alps.

In the town of Volterra, about 30 miles southwest of Florence, are massive paving stones. Volterra is a classic Tuscan hill town with a history that stretches back to Etruscan times. The Etruscans built several gates, one of which remains and still has figures carved out of basalt, though much weathered. The well-worn roads are made of sediments rich in fossil shells, the largest of which are the size of a deck of cards.

I have not visited my final site of European cobbles. I learned about it from Michael Welland, who writes the blog, Through the Sandglass. Here is what he had to say about the old French Mediterranean city of Narbonne. “Awe-inspiring, the oldest cobbles are the pavement of the great road of the Roman Empire (Narbonne was a major regional capital), the Via Domitia. This section of the road was uncovered not that long ago in the town square. This is really hairs-on-the-back-of-your-neck stuff as you gaze at the wear of traffic 2000 years ago.” He thought they were highly indurated marbles.

  1. Interesting to see the various cobblestones—and to think I thought they all looked like the ones in Seattle.


  2. This isn't about this specific post, but about the interesting cumulative effect of reading your blog. I am beginning to see and hear things differently. The Canadian radio talk show As It Happens ran a piece (4/16/2009 on NPR) on a Kingston, Ontario department store (S & R Dept. Store) closing its doors. Sad, but what really drew me in was the brief mention that it is housed in a building constructed in 1817 of limestone. A bit of research revealed that Kingston is called the Limestone City because of its many limestone buildings. Thanks for opening a new source of interest.
