What is the history of granite?
Ancient Egyptians made columns, walls, and floor veneers out of granite. In most historic cities in Europe, South America, and Mexico, granite blocks also have been used for centuries. For example, in the 17th century cobblestones were laid to create roadways. But because of the excessive noise of horses’ hooves and the rough carriage rides on these irregular stones, builders switched to quarried blocks of granite, called setts. (In fact, sett paving is thought to date to ancient Rome.)
I think some of the most beautiful granite used in gardens today are those which were quarried and used by stone cutters and masons hundreds of years ago, granite block and pavers from bridges, foundations, and New England mills. Not only is a piece of history attached to these reclaimed vintage pieces, the exposure to the elements and years of wear and tear also creates a unique patina.

Granite pavers and cobblestones are handsome, durable choices for driveways and patios. Granite slabs make sturdy stairs and stoops. Granite boulders add visual interest to a landscape.
