Host your special event or wedding at the Carnegie Institution for Science. This historic building's solid, neoclassical facade is an impressive presence. Its monumental portico is surmounted by a flat-top roof and supported by Ionic columns. Huge marble urns, copies of originals in the Vatican Collection, flank the entrance steps. Massive bronze doors at the top lead inside to a two-story rotunda, framed by large Corinthian columns and an elliptical side staircase. Large offices with twelve-foot ceilings and elaborate cornices line the rotunda on both floors. Natural light plays across the rotunda floor, as well as the wide hallways and second-floor library, swept in from a sophisticated system of skylights not visible from the Sixteenth Street entrance.
