The auditorium is one of the largest auditoriums in North Carolina, with more seats than auditoriums at many major universities (UNCG's Aycock Auditorium was originally built to seat only a hundred or so than the Williams auditorium seats). The "auditorium seats over 2100 and includes a balcony that makes it reminiscent of a traditional downtown theatre. Because it is the largest facility of its kind in Alamance County, the auditorium is used for many outside performances and graduations, as well as Williams's school functions" ("Williams High Auditorium" greeting card, back side). At the time of construction, it was said to be second only to Raleigh's Memorial Auditorium in terms of seating capacity. includes a pipe organ donated by the Williamses, a rarity among even older high schools, which is generally used only during commencement exercises. Its dedicatory concert was performed by world-renowned concert organist Virgil Fox on October 19, 1951. The Burlington newspaper billed the organ as one of "the largest organ installations in the South." French organist Pierre Cochereau has performed there as well. The auditorium was the first part of the facility to be completed, and was used for the Burlington High School Class of 1951's commencement ceremony before the completion of the rest of the building. Thrice in the 1950s, the Miss North Carolina Pageant was held here.
