Chalmers Street has the longest stretch of cobblestones in the city

Every stone underfoot on this lane arrived here by sea. The Charleston peninsula has no natural stone of its own, as the ground is made of sand, mud, and oyster shells. During the colonial era, ships arriving from across the Atlantic to collect rice, indigo, and cotton traveled light on their way into the harbor. A ship without a heavy load is unstable in open water, so sailors filled the holds with river rock to serve as ballast.

Once a ship docked at the wharf, that rock became dead weight that took up space meant for profitable cargo. Instead of dumping the stones into the water and clogging the harbor, the city used the ballast to pave the streets. These stones are rounded river rocks of different sizes and colors rather than flat, quarried blocks. While most of the city has been paved over with modern materials, this stretch between Meeting Street and State Street remains the longest original cobblestone path in Charleston.

Halfway down the block stands the house at number 17, known as the Pink House. Its walls are built from eighteen-inch blocks of Bermuda stone. This coral stone is naturally pink and was likely cut to size before being shipped to the harbor. The house is 1,007 square feet and is among the oldest buildings in South Carolina. Only the Colonel William Rhett House is older.

The exact date the house was built is a matter of debate, with estimates ranging from 1694 to 1745. Over the centuries, the building has served as an art gallery, a law office, and a private residence. Local tradition holds that it began as a colonial tavern, serving the sailors who had just finished unloading the very stones that pave the street outside the door.
