Lumen Field was built over a roughly two‑year period, from 2000 to 2002, on the former Kingdome site in Seattle.

Quick Scoop

  • Construction of Lumen Field took place between 2000 and 2002, following voter approval of public funding in 1997.
  • The stadium officially opened on July 28, 2002, marking the completion of the construction phase.
