Hollins University is a four-year private institution of higher education located on a 475-acre campus on the border of Roanoke and Botetourt counties in the U.S. state of Virginia. Founded in 1842 as Valley Union Seminary in the historical settlement of Botetourt Springs, it is one of the oldest institutions of higher education for women in the United States. Hollins has since evolved into a full university with approximately 800 enrolled undergraduate and graduate students.
