Ornamental Bronze-colored Metal Lattice at the National Museum of African American History and Culture

The design of the National Museum of African American History and Culture is strikingly different than the "traditional" Washington, D.C. buildings. Here is a short description of the building from the Smithsonian website:

From one perspective, the building’s architecture follows classical Greco-Roman form in its use of a base and shaft, topped by a capital or corona. For our Museum, the corona is inspired by the three-tiered crowns used in Yoruban art from West Africa. Moreover, the building’s main entrance is a welcoming porch, which has architectural roots in Africa and throughout the African Diaspora, especially the American South and Caribbean. Finally, by wrapping the entire building in an ornamental bronze-colored metal lattice, Adjaye pays homage to the intricate ironwork crafted by enslaved African Americans in Louisiana, South Carolina, and elsewhere. 

Here is a YouTube video showing the construction of the building.
