What are Cobblestones?


If you’ve ever wondered why your car trembled like it was scared while driving down Germantown Avenue, there’s one answer: The combination of the trolley track and cobblestones.

So you know what a trolley track is, but what are cobblestones?

Cobblestones are river rocks that were commonly used to pave streets in more ancient times. They are made from highly durable stones, usually basalt or granite. Eventually, because there were newer ways of paving and because the newer ways were cheaper, easier to install, and meant for a smoother ride, cobblestones lost their popularity. Many of the existing cobblestone roads were paved over with layers of concrete and asphalt.

But on Germantown Avenue, the streets are still lined with visible cobblestones.

“These cobblestones were put in, in the late 19th century,” said Gene Stackhouse, a Germantown Historical Society volunteer who works as an historian and a genealogist. “But starting in the 1700s, there were cobblestones all over Philadelphia. The street I grew up on in Kensington had cobblestones on the street until after World War II.”

The makings of Germantown’s cobblestones were unique. So unique that no one wanted to figure out a way to remove them.

“These cobblestones were laid by Italian immigrants who specialized in masonry work and no one ever wanted to take them up,” Stackhouse explained. “In the ’70s they were [instead] fixed, where as most streets in Philadelphia [turned to] asphalt.”

But not everyone has given up on trying to get the cobblestones removed.

“Picturesque” and “historic” were terms Stackhouse used to explain why residents wanted to keep the cobblestones, but he does not feel the same way.

“I think they’re a pain,” Stackhouse said. “I don’t drive on [Germantown] Avenue [because of them].”

Though Stackhouse thinks they’re a bother, Germantown is one of few neighorhoods to still have cobblestone roads. The battle over whether to put forth the time and money to remove them. That decision could last another century.

  1. Paving stones, although they may not be nice to drive on, add character to old neighborhoods. Although I am in the paving business, I would never like to see all the old cobblestone disappear.

  2. Hate to tell you this, but the paving on Germantown ave is not cobble stone but Belgian block. If you want to see cobble stone paving go to Dock st in center city between 3rd and Walnut street. The street there had been rebuilt using cobble stone.

  3. Roman is right, these are belgian block but many people call them cobblestones. Cobblestones are rounded from rivers and were used much earlier. You might see them underground if PWD has to visit your block!

  4. I have done my driveway with cobblestones. I was lucky enough to receive them from an excavating company who tore up some streets in Philadelphia for $1.00 each

  5. Belgian Block, not cobblestone. Getting the topic wrong seems like a pretty serious mistake.
