Washington Monument
The faint color seam partway up the shaft marks where construction stopped for 23 years.

The exterior marble comes in three visibly different shades because funding collapsed and the Civil War intervened, halting work from 1854 to 1877. The result is a 555-foot obelisk whose interrupted history is legible from the ground. It held the title of world's tallest structure from 1884 until the Eiffel Tower claimed it in 1889 — a reign of just five years.
What to look for
- The marble color change on the shaft — the clearest evidence of the 23-year construction pause
- The tiny aluminum pyramid capping the very apex, with inscriptions on all four sides
- Eight observation windows cut into the pyramidion near the top, paired with eight red aircraft warning lights
An elevator runs up the hollow center; iron spiral stairs line the interior walls for those who want to climb.
