what historic building in Washington, D.C. is located near the canal who's primary cargo is coal
Chesapeake and Ohio Canal The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the "Grand Old Ditch," operated from 1831 until 1924 along the Potomac River from Washington, D.C., to Cumberland, Maryland. The canal's principal cargo was coal from the Allegheny Mountains.
Lincoln Catafalque The Lincoln catafalque is a catafalque hastily constructed in 1865 to support the casket of Abraham Lincoln while the president's body lay in state in the Capitol Rotunda in Washington, D.C. The catafalque has since been used for all those who have lain in state in the Capitol Rotunda, as listed below. When not in use, the catafalque is kept in the United States Capitol Visitor Center in a small vaulted chamber. It was previously kept in an area called Washington's Tomb, which was originally intended, but never used, as the burial place for George Washington, the first President of the United States.
