The buildings of our Nation's Capital have been constructed with rocks from quarries throughout the United States and many distant lands. Each building shows important features of various stones and the geologic environment in which they were formed.
This booklet describes the source and appearance of many of the stones used in building Washington, D.C. A map and a walking tour guide are included to help you discover Washington's building stones on your own.
When choosing a building stone, architects and planners use three characteristics to judge a stone's suitability. It should be pleasing to the eye; it should be easy to quarry and work; and it should be durable. Today it is possible to obtain fine building stone from many parts of the world, but the early builders of the city had to rely on materials from nearby sources. It was simply too difficult and expensive to move heavy materials like stone before the development of modern transportation methods like trains and trucks.
