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.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.[2] Notable hand-carvings by Milani include the History of the World relief at the Pennsylvania State Capitol and the four eagle sculptures flanking the entrances of the Knoxville Post Office.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).[3] The showroom's interior includes an entrance hall with polished travertine and frescoed plaster walls and a hand-carved marble rosette.
