Ground Zero, site of the 9/11 tragedy.

The Lincoln Memorial is in Washington DC, just west of the Washington Monument (posted earlier).

The Lincoln Memorial was built to resemble a Greek temple. It has 36 Doric columns, one for each state at the time of Lincoln’s death. A sculpture by Daniel Chester French of a seated Lincoln is in the center of the memorial chamber.

Thanks Spaz

A rather sombre one here. The Arlington National Cemetery is where thousands of American service men and women are buried. Those little ridges along the grass aren’t ridges. They are all graves.

Thanks R.B. Boyer, djojo, Keith, Spaz & Stranger.

The Boeing factory building is the biggest building (by volume) in the world. The original building was constructed in 1966 and completed in 1969. Its footprint now covers 98.3 acres and is where Boeing constructs their 747, 767, and 777 planes.

Thanks Andrew, JReykdal, Brian, Siavash Shiva, Shawn C, Ed Hirsch, Nathaniel, Chris & Ballard.
