it was soon leveled for a new housing development, but the Croghan-Schenley rooms were spared. In 1955, the rooms, donated by Miller, were dismantled and rebuilt in the Cathedral, except that the original ceilings had to be lowered about 8 inches to accommodate the available space. In 1982, the rooms were refurbished to their 19th century glory. Highlighting the ballroom are the hand-cut glass chandelier and four wooden, hand-carved Greek columns, surviving examples of western Pennsylvania's Greek classical revival period popular with those of means in the 1830s. The Croghan-Schenley rooms are the last extant vestiges of the estate of Mary Schenley, who before she died gave much of her holdings and property to the city of Pittsburgh—including Schenley farms, where the Cathedral sits, and Schenley Park. Stories tell of a ghost, speculated to be that of Mary Schenley, that is said to roam the Ballroom and Nationality Rooms. The doors to the rooms are locked every night, but furniture is sometimes said to be found rearranged by daylight staff. The swinging of the chandelier has been said to indicate her presence. Frick Auditorium The Frick Auditorium is a lecture hall in room 324 of the Cathedral of Learning. Originally conceptualized as the Fine Arts Lecture Room intended to complement the Fine Arts Department then located on the seventh floor, the room was completed in 1939 and features stone mullions, chambranle, and other trim as well as wooden lecture seating and a coffered ceiling. A centerpiece element in the room is a Nicholas Lochoff reproduction of The Resurrection by Piero della Francesca that was purchased for the lecture hall by Helen Clay Frick. Frick would later donate a large collection of Lochoff reproductions to the university which are on display in the Nicholas Lochoff Cloister in the university's Frick Fine Arts Building. Humanities Center The University of Pittsburgh's Humanities Center, part of School of Arts and Sciences, is housed in the Cathedral of Learning's room 602, which was a sixth-floor space once occupied by the Darlington Memorial Library. Following digitization and protective storage of the library's materials, its space was renovated in 2009 by architect Rob Pfaffmann to house the center, which now includes office space for staff and visiting fellows. The Humanities Center space retains much of the original character and many of the antique furnishings originally bequeathed to the university by the Darlington family, and features moldings and
