The Carnivora House, also called the Animal House or the Lion House, is constructed at the National Zoological Park. The first permanent structure in the Park, and constructed of locally quarried grey gneiss stone, it was designed by Boston architect William Ralph Emerson. The design is somewhat modified to suit the extingencies of the appropriation available, it being impracticable to erect more than a portion of the structure.
