PORTLAND, Ore. (KOIN) — In most people’s attics, you’ll find years of family memories and history. But, did you know Oregon has its own attic where thousands of items are carefully stowed away?

The Oregon History Center Vault is a massive, climate-controlled building. The location is kept secret — but Jeff Gianola is taking you inside as he uncovers Oregon’s treasures.

There are 3 things that you won’t find in the Vault, however — those valuable items are always kept in this briefcase.
