The Lincoln Memorial was built to resemble a Greek temple. It has 36 columns, one for each state at the time of Lincoln's death.

The statue of Lincoln was carved from 28 interlocked blocks of crystalline white Georgia marble and is 19' high and 19' wide. The south wall of the monument is inscribed with the Gettysburg Address.
It's interesting what you can learn from the back of post cards! ;0)
Inside the memorial, the 12-24 mm wide-angle lens I got came in really handy. I didn't bother to put the circular polarizer on at all because I can't figure out an efficient way to work it.
