(those built between 1938 and 1957) took between three and ten years to complete, and cost the equivalent of US$300,000 in 2006 dollars. More recent rooms have cost in the range of $750,000 and up. Classrooms Proposed rooms There are six nationality rooms in various stages of planning to add to the current 31. Other notable spaces There are several other notable facilities and rooms within the Cathedral of Learning. In addition, these spaces do not fall under the auspices of the Nationality Rooms program. Babcock Room The Edward V. Babcock Memorial Room is a plush, carpeted, wood-paneled conference room constructed on the 40th floor for use as the University trustees' boardroom. Funded by a Babcock family grant of $327,000 ($ in dollars) and dedicated in November 1958, all of the room's features are original, except for the lighting, furniture and carpeting. The room's square shape is modified by four alcoves, in one of which is a portrait of Babcock by Malcolm Stevens Parcell. The walls, featuring intricate geometric patterns, are paneled in Appalachian white oak with burled walnut inlays and touches of rosewood. The windows, adorned by leaf-patterned curtains, boast a spectacular panoramic view of the surrounding area. The room is also adjoined by a kitchen. Access to the room is limited to a spiral staircase and an elevator, both requiring a key, that originate on the 36th floor. During the early 1970s at the height of student activism, a group of protesting students attempted to barricade the room during a trustees meeting. Today, the trustees have outgrown the room and generally meet in the Assembly Room of the William Pitt Union. The Babcock room now serves as a seminar and meeting room and is also used for special events. A pair of peregrine falcons nests on the balcony outside the room. Braun Room Following the opening of the Cathedral of Learning, the offices of the Dean of Women moved to the 12th floor of the Cathedral in 1938. The interior was unfinished but Dean Thyrsa Amos envisioned a dignified and beautiful space for women to meet. When Dean Amos died in 1941, the new quarters were still unfinished. The Alumnae Association created the Thyrsa W. Amos Fund to plaster the walls and to furnish Room 1217 in her name. Room 1217 was never finished, but after World War II the other rooms on the twelfth floor were completed
