Our mammoth expansion

The Museum’s last expansion in 2001-03 transformed it into the Gem State’s premier informal education center. Since then, MOI has continued to grow and mature, and is now embarking on the next step. That means an enhanced ability to keep exhibits fresh, remain open during transitions, and most importantly, tell your stories how they deserve to be told. It means MOI can bring the world to Idaho, and Idaho to the world better than ever before.

Note: MOI will remain open during regular business hours throughout the entire construction process.


Phase 1: More than 20,000 square feet of new space, including:

  • A larger two-story atrium for international traveling exhibits
  • An improved Maeck Family Foundation Education Center inside the main building
  • Customizeable exhibit and event space to keep things fresh
  • Food options for patrons who need a break
  • More available parking (95 spaces total)
  • Anticipated opening: summer to fall 2019

Phase 2: Interior modifications to current space, including:

  • Almost triple the space for Idaho/regional exhibits
    • Planned new permanent exhibit: The Way Out West
  • An improved accessions, conservation, and research workspace
  • The ability to remain open during exhibit transitions
  • Improved flow
  • Anticipated opening: spring to summer 2020


The Museum of Idaho needs your help to create The Way Out West, a massive new exhibition to engage, inspire, and celebrate our region’s extraordinary heritage. One way to contribute is by purchasing a custom-engraved brick for our patio area with a tax-deductible donation of either $100 or $500. For a limited time, your brick also comes with 50% off a general membership to MOI.

For other ways to contribute, please contact MOI Director of Development Nick Gailey (208-522-1400 x 3013 or
