Consultant to the Architect of the Capitol for the conservation of four monumental skylights in the Senate and House Grand Staircases. These windows are rare examples of pre-Civil War American stained glass fabricated by the Gibson brothers from 1858 through 1861. Femenella prepared condition reports and conservation proposals; development and execution of emergency removal and temporary storage plan to mitigate impending health and safety issues due to the advanced state of deterioration of the stained glass panels. We fabricated faux copies of stained glass panels printed onto acrylic panels and installed into the skylights as a temporary stop gap until the funds can be raised for proper conservation of these national treasures.
