Top 4 Indiana limestone monuments

American homes might make use of plenty of brick, but there's only one stone known as the Nation's Building Stone: Indiana Limestone. 

Even today, this unique limestone, which can be found anywhere from Bedford to Bloomington, is used to take care of America's every building need. According to the Indiana Geological Survey, nearly 2.7 million cubic feet of it is quarried each year and used on countless different buildings. You've probably looked at Indiana Limestone before and not even realized it. 

What follows is a short list of just some of the most famous structures to which Indiana Limestone has contributed. 

1. The Pentagon

The Pentagon isn't simply the location of the United States Department of Defense – it's also a fantastic showcase of the strength and durability of Indiana Limestone. 

Its malleability was especially handy when the Pentagon required repairs on its western side. Because it is a freestone – or one that has no preferential direction for splitting – Indiana Limestone can be carved, cut and shaped into a huge range of shapes and sizes, simplifying the task at hand. 

2. The Empire State Building

It was the fittingly named Empire Quarry that provided the 18,630 tons of limestone needed to construct the Empire State Building, the world's tallest skyscraper at the time.

The story goes that the colossal structure was originally built as part of a competition between General Motors' John Jakob Raskob  and Walter Chrysler of Chrysler to see who could build a taller tower. Today the Empire State Building is an essential part of the New York skyline and one of the most important pieces of American architecture, and it's still standing strong – despite being struck by lightning an average of 25 times a year.

3. Monument Circle

Also known as the State Soldiers' and Sailors' Monument, this hallowed tribute to the veterans of Indiana stands at the centre of Indianapolis as a reminder of the ultimate sacrifice made by our young men and women in uniform. 

At nearly 285 feet tall, the impressive monument is not much shorter than the more famous Statue of Liberty. Limestone was used to create the monument itself, as well as some of the sculptures that surround it.

4. Lincoln Memorial

Indiana Limestone was crucial for the creation of one of the most recognizable and widely known structures in the national capital – the Lincoln Memorial, which was completed between 1914 and 1922. 

A variety of stones were used to create the memorial, but Indiana Limestone was used for its interior walls and columns, which measure in at a height of 50 feet. 

Just because these structures have stood the test of time doesn't mean your own personal limestone will. For limestone protection around your own home, you'll want to use Dry-Treat's META CRÈME™ to protect it from stains and water damage.
