Indiana Limestone is a natural product formed some 300 million years ago in the shallow seas that covered Southern Indiana. This Mississippian-age grainstone has a very uniform texture and grade, and it has gained worldwide acceptance as a premier dimension stone. Indiana Limestone weathers naturally over time, and the stone's color mellows and blends into a pleasing natural patina. With no artificial coloring agents to fade and no reinforcement rods to rust, the appearance of Indiana Limestone actually improves with age.
In 1827, the first organized quarry opened in Monroe County in Stinesville, Indiana, and the stone has been in constant use since then. With the arrival of the railroads to the area in the mid-1850s, the use of Indiana Limestone spread across the nation. The ability of Indiana Limestone to readily adapt to various architectural styles, along with its pleasing natural color, ease of shaping and durability are advantages that have all worked together to maintain the stone's popularity throughout the years.
