On September 19, 1957, the United States detonated a 1.7-
kiloton nuclear weapon in an underground tunnel at the
Nevada Test Site, a 1,375-square-mile research center
located 65 miles north of Las Vegas. 
 

The test, known as Rainier, was the first fully contained
underground detonation and produced no radioactive
fallout. A modified W-25 warhead weighing 218 pounds
and measuring 25.7 inches in diameter and 17.4 inches
in length was used for the test.

Rainier was part of a series of 29 nuclear weapons and
nuclear weapons safety tests known as Operation
Plumbbob that were conducted at the NTS between
May 28, 1957, and October 7, 1957.

On September 18, 1793, President George Washington laid the cornerstone to the United States Capitol building, the home of
the legislative branch of American government.

The building would take nearly a century to complete, as
architects came and went, the British set fire to it (above) 
and it was called into use during the Civil War.

Today, the Capitol building, with its famous cast-iron
dome and important collection of American art, is
part of the Capitol Complex, which includes six
Congressional office buildings and three Library
of Congress buildings, all developed in the 19th
and 20th centuries.
