The Lorillard Snuff Mill now known as the Lillian and Amy Goldman Stone Mill, is the oldest existing tobacco manufacturing building in the United States. It was built around 1840 next to the Bronx River to supplement an earlier building of the same function. The schist that makes up its walls was quarried locally. It was declared a National Historic Landmark in 1977 and is located inside the New York Botanical Garden, itself an NHL.
