A Tiny Timeline

  1. January 1887 – Work on the foundations and structure begins.
  1. July 1887 – Assembly of the four iron legs starts above the ground.
  1. April 1888 – First floor completed.
  1. August 1888 – Second floor completed.
  1. March 31, 1889 – Top and overall assembly finished; the tower is effectively complete.

Even by today’s standards, putting up a 300‑meter iron tower in just over two years was seen as record‑breaking speed at the time.
