Indiana Limestone

Indiana limestone — also known as Bedford limestone — is a common regional term for Salem limestone, a geological formation primarily quarried in south central Indiana, USA, between the cities of Bloomington and Bedford.

Bedford, Indiana, has been noted to have the highest quality quarried limestone in the United States. Salem limestone, like all limestone, is a rock primarily formed of calcium carbonate. The limestone was deposited over millions of years as marine fossils decomposed at the bottom of a shallow inland sea which covered most of the present-day Midwestern United States during the Mississippian Period.

History

Sanders Quarry in Monroe County, Indiana

Native Americans were the first people to discover limestone in Indiana. Not long after they arrived, American settlers used this rock around their windows and doors and for memorials around the towns. The first quarry was started in 1827, and by 1929 Hoosier quarries yielded 12,000,000 ft3 (340,000 cubic meters) of usable stone. The expansion of the railroads brought great need for limestone to build bridges and tunnels and Indiana was the place to get it.

American architecture of the late 19th and early 20th century included a lot of limestone detail work on buildings, but as architectural styles changed, so did the demand for limestone. Salem limestone was officially designated as the state stone of Indiana by the Indiana General Assembly in 1971.[1] With the Arab Oil Embargo of 1973, the price of alternative building materials skyrocketed so Indiana limestone reemerged as an energy-efficient building material.[2]

Purpose

Indiana limestone is part of a high-end market. It is mostly used on the exterior of homes and commercial buildings. With the impact of acid rain it is not used in monuments as it was in the 19th century. Many of Indiana's official buildings, such as the State capitol building, the monuments in Downtown Indianapolis, the Indiana University School of Law in Indianapolis, many buildings at Indiana University in Bloomington, and the Indiana Government Center, and most of the state's 92 courthouses are all examples of Indiana architecture made with Indiana limestone. Indiana limestone has also been used in many other famous structures in the United States, such as the Empire State Building, the Pentagon, Yankee Stadium, and the Washington National Cathedral. In addition, 35 of the 50 state capitol buildings are made of Indiana limestone.[3]

Notable buildings

Buildings such as the National Cathedral, Biltmore Estate, Empire State Building, The Pentagon, Hotel Pennsylvania and the United States Holocaust Memorial Museum feature Indiana limestone in their exteriors. Indiana limestone was used extensively in rebuilding Chicago after the Great Chicago Fire. Built in 1959, the architecturally significant St. Augustine's Episcopal Church uses Indiana limestone in the interior. The Saint Sava Serbian Orthodox Church in Merrillville, Indiana consecrated in 1991 and awarded a Gold Medal Award for Excellence in Masonry Design uses Indiana limestone on its exterior facade. New Yankee Stadium in The Bronx, New York, opened in 2009, extensively uses Indiana limestone paneling on its exterior facade. The original 1930s buildings of Rockefeller Center use limestone from Bedford. In 1955 the Tennessee State Capitol exterior was renovated using Indiana limestone to replace the poorer quality Tennessee limestone that had started to deteriorate. Indiana limestone has been particularly popular for the construction of university buildings. The Neo-Gothic campus of the University of Chicago is almost entirely constructed out of Bedford, Indiana limestone; in keeping with the trend of post-Fire buildings using the material. The campus of Washington University in St. Louis, both new construction and its original buildings, makes use of Indiana limestone (along with Missouri Red Granite) in its collegiate gothic architecture. The majority of Indiana University, Bloomington was constructed out of limestone. In addition, many buildings on the north side of Michigan State University use Indiana limestone. The Cathedral of Learning, a 42-story neo-gothic skyscraper that is the largest educational building in the Western Hemisphere, along with other nearby buildings of the University of Pittsburgh, are clad in Indiana limestone. The St. Anthony Society Chapter House at Yale also is built of Indiana limestone.[4] Both structures of the Kenosha County Courthouse and Jail in Kenosha, Wisconsin, were built out of the limestone. The rock was used as far north as the Hotel Macdonald in Edmonton.
