Cobblestones of the market place of Lomnice nad Popelkou.Cobblestones were largely replaced by quarried granite setts in the nineteenth century. Cobblestone is often wrongly used to describe such treatment. Setts were relatively even and roughly rectangular stones that were laid in regular patterns. They gave a smoother ride for carts than cobbles, although in heavily used sections, such as in yards and the like, the usual practice was to replace the setts by parallel granite slabs set apart by the standard axle length of the time.
In older U.S. cities such as Boston, Pittsburgh, New York City, San Francisco, Baltimore, and Philadelphia, many of the older streets are paved in cobblestones and setts (mostly setts); however, many such streets have been paved over with asphalt, which can cracks and erode away due to heavy traffic, thus revealing the original stone pavement.

Many cities in Latin America, such as Buenos Aires, Argentina; Zacatecas and Guanajuato, in Mexico; Old San Juan, Puerto Rico and Montevideo, Uruguay, richly influenced by many European architectural features, are well known for their many cobblestone streets, which are still operational and in good condition. They are still maintained and repaired the old fashion way, by placing and arranging granite stones by hand.

In the Finger Lakes Region of New York State, the retreat of the glaciers during the last ice age left numerous small, rounded cobblestones available for building. Pre-Civil War architecture in the region made heavy use of cobblestones for walls. Today, the fewer than 600 remaining cobblestone buildings are prized as historic locations, most of them private homes. They are clustered south of Lake Ontario, between Buffalo and Syracuse. There is also a cluster of cobblestone buildings in the Town of Paris, Ontario. In addition to homes, cobblestones were used to build barns, stagecoach taverns, smokehouses, stores, churches, schools, factories, and cemetery markers. The history of building with cobblestones and 17 driving tours to see the remaining structures are found in "Cobblestone Quest - Road Tours of New York's Historic Buildings".
