Quarrying on this site began in 1690 by James Stanclift, who contracted with the town of Middletown to build stonework in exchange for a deed of land. Commercial quarrying started in 1783 when the Brainerd Quarry Company began operations. During the peak of the brownstone era, more than 1500 workers were employed by the quarries, which shipped stone on their own ships for eight months out of the year.
