Smithsonian Institution

The Smithsonian Institution, established in 1846 "for the increase and diffusion of knowledge," is a group of museums and research centers administered by the United States government.

History
The Smithsonian has a Captain America’s wing, inside it there were several painels displaying his life before the Project Rebirth, his friendship with Bucky Barnes, his great deeds on World War II, his uniform and his motorcycle.

After the battle on the Triskelion, the Winter Soldier goes to Captain America’s wing of the Smithsonian, where he intensely looks at the part of the exhibit about himself, implying he is starting to remember about his past as Bucky Barnes.
