Project of the Week Mini Description & Details
Situated on five acres on the National Mall in Washington, D.C., the $540 million National Museum of African American History and Culture seeks to understand American history through the lens of the African American experience. The Smithsonian’s first LEED Gold project, it was first proposed by black Civil War veterans 102 years ago and after much debate and opposition from legislators, the museum was finally approved by an Act of Congress. Championed by deceased Republican U.S. Senator Sam Brownback and Democrat Georgia Representative and civil rights campaigner John Lewis, it opened on September 24, 2016. President Obama dedicated the museum and Representative Lewis called it a place that celebrated “the dignity of the dispossessed.” The interior is composed of five large gallery spaces containing over 35,000 artifacts related to African American history, community, and culture, and covers slavery, civil rights, sports, historic black communities, music, visual arts, and more.
Designed by Freelon Adjaye Bond/SmithGroup, the 420,000 square foot building has a three-tiered shape and is inspired by the Yoruban Caryatid, a traditional wooden column which features a crown or corona at its top. Reaching toward the sky, the bronze-colored filigree corona expresses faith, hope and resiliency. Below, visitors enter through a grand “porch” at the south side. The Porch is an outdoor welcome area and the 175-foot-long steel and concrete canopy shades visitors with its upward tilt. An extensive greenroof planted with pre-vegetated sedum mats from Moerings USA/Sempergreen covers the porch’s overhang. Much of the north lawn is a large intensive greenroof which covers the galleries below and the glass oculus that juts up from the grounds to help illuminate the underground portions. At night, the corona glows, presenting stunning views of the museum from a variety of vantage points in and around the Mall. The location and design of the National Museum of African American History and Culture represent the past, present, and future of the African American experience in ways that are both tangible and symbolic.
