Webcams mounted on O'Neill Library (top) and Ignacio Hall (bottom) capture the south side and back, respectively, of St. Mary's Hall, while the 96-year-old building that serves as the Jesuit residence undergoes two years of interior and exterior renovations. The work commenced in mid-January 2013. Beginning with the south facade, some 18,000 pieces of cast stone will be removed and replaced; the roof will be repaired; and new windows will be installed. Inside the building, floors two, three, and four will be gutted as will the ground floor and the attic. The first floor, which contains the chapel and dining room, will be refurbished, but its layout will remain unchanged. The renovated south wing (facing O'Neill Plaza) will house the communication and computer science departments and the Woods College of Advancing Studies.
During construction, members of the Boston College Jesuit community will reside in a University-owned apartment complex on Commonwealth Avenue. Masses previously scheduled in St. Mary's Chapel have been relocated to Gasson Commons, the former Honors Library, for the duration of the renovations.
