Located in upscale Orange County, California, the Crystal Cathedral is the world’s largest glass building.  Being one step ahead of mother nature, architect Philip Johnson used silicone-based glue to attach the glass panes to the structure so that it could withstand earthquakes.  The Crystal Cathedral is currently under ownership by the Roman Catholic Diocese of Orange and is being remodeled to accommodate Roman Catholic liturgy.  It is expected to re-open in 2017, and renamed Christ Cathedral.
