The Howard M. Metzenbaum Courthouse, designed by NY architect Arnold Brunner, is an example of French Beaux-Arts architecture.  The building was added to the National Register of Historic Places in 1974. The granite building is ornamented with bronze window frames, barriers, and lanterns, including the large doorway torchiers that were the subject of this conservation effort. Two 10’ tall bronze torchiers stood flanking the doorway on the northeast corner of the building. Standing on either side of the granite stairway, on 3’ tall granite bases, the bronze lanterns displayed typical corrosion patterns of green copper oxide and black mineral crusts.

Each lantern consisted of seven parts which assemble as a stack of elements joined by Roman joints. The two matching lanterns which once stood at the southeast entrance were missing from the granite steps.  The two existing historic lighting standards were conserved, and used as models during the creation of two bronze cast reproductions.  LED lighting and replicas of the original glass globes were also included in the restoration/reproduction.
