史密森尼学会的非裔美国人历史和文化国家博物馆(NMAAHC)是几十年来为纪念黑人历史和文化不断努力的成果。博物馆位于国家广场，在意义非凡的选址和美国悠久却不为世人注目的非裔美国人的文化传统之间，架起一座桥梁。

The Smithsonian Institution’s National Museum of African American History and Culture (NMAAHC) is the result of a decades-long journey toward the commemoration of black history and culture. The building, located on the National Mall, establishes a strong connection to both its unique site and America’s long-standing and often overlooked African American heritage.

NMAAHC重新思考21世纪公共建筑的功能，旨在提供全新的用户体验和互动方式。它是新式博物馆的代表：优先考虑叙事方式和特色，生动灵活地讲述不为人知的故事，并为积极的社会变革营造声情并茂的场景。因此，它既是博物馆、纪念馆，亦是跨文化合作和学习的空间。博物馆外形设计受到西非传统雕塑——约鲁巴人女像柱的启发。 “日冕”是博物馆三层外部结构的重点。

The NMAAHC rethinks the role of civic institutions in the 21st century, offering new modes of user experience and engagement. It presents a new form of museum: one that prioritizes cultural narrative and identity and that gives form to untold stories, establishing an empowering emotional context for positive social change. As such, it operates simultaneously as a museum, a memorial, and space for cross-cultural collaboration and learning. The building shape was inspired by the Yoruban caryatid, a traditional West African post or column. The corona at the top of the caryatid was the key design driver for the museum’s three-tiered exterior form.

倾斜的墙壁向上延伸，在国会广场附近的建筑中别具特色，将现代风格展现得淋漓尽致。建筑本身具有气候调节功能。铜质立面与建筑主体脱离，可起到过滤日光，减少吸收的热量的作用。3600个铜质面板的灵感，来源于美国南部许多非裔美国人用于阳台和门廊的铁艺装饰品的设计。倾角与华盛顿纪念碑的17度角相同。

With angled walls reaching upward, this iconic building profile presents a distinctive and complementary presence among its neighboring structures on the National Mall. The form itself works as a passive climate-controlling system. The bronze façade sits away from the building, filtering daylight while reducing its heating effects. The pattern cast into the 3,600 bronze-colored corona panels alludes to the ornate ironwork found in southern cities typically designed and fabricated by Americans of African descent. The angle matches the 17-degree angle of the Washington Monument.

博物馆选址于国会广场最后一块建筑用地，位于是规整有序的国会广场，以及华盛顿纪念碑周围田园风景间的过渡点。对称式设计呼应广场的经典风格，也与绿意盎然的蜿蜒小径融为一体。

Located on the National Mall’s last buildable parcel, the museum is positioned at the transition point between the highly ordered geometry of the mall and the pastoral grounds surrounding the Washington Monument. Responsive to both conditions, the building footprint is symmetrical, relating to the classical language of the mall. Conversely, the site design mimics the organic, curved pathways of the grounds.

备受期待的展品按历史事件的时间顺序展出，让观众无需对应时间轴，便能了解各展品的时间次序。从修复后的奴隶船压舱物、种族隔离时代的轨道车、两个奴隶时代的客舱，以及安哥拉监视塔等，都在该空间展览。地下建筑部分，三层挑高的历史文化廊，既有纪念意义，又发人深省。

Several prominent artifacts are exhibited in the space in order of historical timeframe, allowing viewers to understand their juxtaposition in time without the use of a graphic timeline. Of note, a ballast recovered from a confirmed slave ship, a restored segregation-era rail car, two slave-era cabins, and the Angola Guard Tower form exhibits in the space. Below ground, the ambiance is both monumental and contemplative, expressed by the triple height history gallery.

展品设计以指向性技术、定位和低视角为主，营造老少皆宜的参观环境。展览以情感为主题，包括迁徙、回忆和再生。建筑主入口设有宽敞的门廊和景观池，迎接从国会广场前来的观众。

To reach a multi-generational audience, exhibit design focused on intentional technology, positioning, and lower viewing angles to create experiences that are welcoming to all. The exhibits were driven by a number of emotional themes that included resilience, movement, and memory. The building’s main entrance features a sweeping front porch with a reflecting pool, welcoming all who approach it from the National Mall.

技术悄然隐匿于展品中。冥想中庭内，水柱从13.7米高的圆形天窗倾泻而下。这项工程和设计的挑战在于技术“隐形”，让观众在陷入深深的沉思时，获得耳目一新的体验。

Technology was implemented in ways that are not readily apparent. The Contemplative Court showcases a cylindrical cascade of water flowing from an elliptical skylight 45 feet above. This engineering and design challenge focused on “invisible” technology to allow for an emotionally refreshing experience many patrons need as they make their way through potentially disturbing content.

博物馆占地3万多平方米，其设计与建造是美国最庞大、最复杂的建筑项目之一。由于60%的建筑位于地下，设计师与工程师需在场馆周围设计延续的挡土墙，向地下延伸的最大深度近20米——以确保置于华盛顿地区沼泽中地基的稳固。

The design and construction of the nearly 400,000-square-foot museum, was one of the largest and most complex building projects in the U.S. when it was built. With 60 percent of the structure underground, designers and engineers had to create a continuous retaining wall around the perimeter of the site—extending 65 feet down at its maximum height—to secure the building’s foundation in the marshland below Washington, D.C.
