Established as a subsidiary of the John J. Craig Company in 1914, the facility's marble products were used in the construction of numerous monumental buildings across the United States during the 1930s and 1940s.

Although Candoro closed in 1982, independent marble fabricators continued using the facility until the early 21st century, when it was purchased by the preservation group, South Knox Heritage.

The John J. Craig Company, which operated several quarries in the vicinity of Knoxville, was one of the region's top marble suppliers during this period.

The showroom is the easternmost building, lying adjacent to Maryville Pike, and is connected to Candora Road by an oft-photographed tree-lined allée.

While the company initially used its own locally quarried stone, it gradually began to rely more and more on marble imported from Europe and South America.

In addition, the Candoro Arts and Heritage Center volunteers will continue to present Vestival on the building's grounds as well as quarterly programming.

The building's facade features a hand-carved cartouche and floral motif and a wrought-iron door crafted by Philadelphia master blacksmith Samuel Yellin (1885–1940).
