I was lucky enough to see this building in person last year when I went to visit Washington D.C. It is very unique and the outdoor metal work is intricate with such a rich history. It was created by lead designer David Adjaye and lead architect Philip Freelon, with their architectural team Freelon Adjaye Bond/SmithGroup.

The  form of the museum is inspired by the three-tiered crowns used in Yoruban art from West Africa. The wrapping of the entire building in an ornamental bronze-colored metal lattice, the architect pays homage to the intricate ironwork crafted by enslaved African Americans in Louisiana, South Carolina, and elsewhere. As seen in the above picture, the inside is beautiful too, with natural light penetrating the inside of the building, peeking though the ornamental lattice. 

At night, the building glows with an iridescence that is mystifying. Right next to the Washington monument it does not overshadow but beams with light just as the bright monument. Although the building is seemingly opaque during the day, the designers and architects did an incredible job letting the ornamental lattice shine day and night on the building.
