Union Station is due east of the White House (directly above
the White House near the top of the diagram on L'enfant's gravestone) at the
intersection of Massachusetts Avenue (the diagonal line going up from left
to right on the far left side) and Delaware Avenue (the diagonal line that
crosses over the Capitol going up from right to left near the top). Atop the
Columbus Monument in front of Union Station is a sculpture of the earth.
The dove in the picture is sitting on southeastern Alaska, near
the top of the globe. The horizontal circumference of the globe approximates
the prehistoric alignment of world wonders.
