Blue Ridge Assembly Historic District, YMCA historic district in Black Mountain, United States

The Blue Ridge Assembly Historic District, near Black Mountain in Buncombe County, North Carolina, holds 29 contributing buildings and one contributing object. Eureka Hall, designed by Louis E. Jallade and built in 1911–1912, is a three-story, seven-bay frame building with a full-height octastyle portico. Around the large central courtyard stand the Gymnasium (c. 1915), Asheville Hall (1926), Abbott Hall (1927) and College Hall (c. 1928), with the Martha Washington Residence (c. 1914), a Craft and Child Care Center (c. 1925) and 19 frame cottages (1913–1927).

The Blue Ridge Assembly was founded as a YMCA conference center, and its buildings went up between 1911 and 1927, among them Eureka Hall (1911–1912, by Louis E. Jallade), the Gymnasium (c. 1915), Asheville Hall (1926), Abbott Hall (1927) and College Hall (c. 1928). Black Mountain College was founded on the site in 1933 and operated there until 1941. The district was listed on the National Register of Historic Places in 1979.

The site functioned as a regional meeting place for educational and religious gatherings throughout the 20th century. People traveled to attend conferences and programs held in the district's assembly halls.

The district is a YMCA conference center near Black Mountain, not a public attraction, so visits depend on attending a program or event there. The 29 contributing buildings and one object cluster around a large central courtyard, with Eureka Hall as the main building; the 19 frame cottages date from 1913 to 1927.

Eureka Hall, the main building of the complex, was constructed in 1911-1912 and blends Colonial Revival and Classical Revival architecture within its seven-bay structure. The architect Louis E. Jallade designed this distinctive building with a three-story timber frame and a full-height columned portico.
