the heraldic symbol of the Virgin Mary, and the purity of Christian teaching. Symbolizing the college, a book occupies the center of the field, bearing the motto of St. Scholastica. It is adapted from the second part of the Book of Proverbs line "Her ways are ways of beauty, and all her paths are peace," and reads in Latin, "." Campuses In addition to the main campus in Duluth, St. Scholastica has sites in St. Cloud, St. Paul and embedded sites in Brainerd, Austin, Cloquet, Inver Grove Heights, Rochester and a virtual campus. The Duluth campus is home to most undergraduate students. The 186-acre campus is set on a hill overlooking Lake Superior. Campus buildings include: Tower Hall, the Science Center, Our Lady Queen of Peace Chapel, Burns Wellness Commons, the 500-seat Mitchell Auditorium, the College Library, the St. Scholastica Theatre, Somers Residence Hall, and nine apartment complexes. A new Health Science Center housing graduate health science programs opened for classes in 2016. The building is at 940 Woodland Ave. in the BlueStone development, about a mile from the main campus. Library The college library provides over 350,000 print and electronic books, full-text journal databases, interlibrary loan services, laptops, wireless Internet access, group study rooms, and quiet study space. It is located on the upper floors of the Romanesque-styled Our Lady Queen of Peace Chapel building. Along with the library, the college archives preserves the written and visual history of the college, as well as housing special collections such as the papers of James Franklin Lewis. Tower Hall Tower Hall is St. Scholastica's castle-like central building. Its origins date to a picnic in around 1907, when the Diocese of Duluth's Bishop James McGolrick commented that the top of the hill at the college's current site was a perfect location for a building. According to the historic records of Sister Agnes Somers, McGolrick and a group of students and sisters climbed to the top of the hill and placed a pile of stones, symbolizing the cornerstone of what would eventually become Tower Hall. In 1906, architects Anton Werner Lignell and Frederick German were hired to draw the plans for the school, Villa Sancta Scholastica Academy, and the motherhouse. Mother Scholastica Kerst disapproved of the plans due to potential defects in the building's design, and the two architects were fired from the project in 1908; it was taken over by Franklin Ellerbe.
