South Carolina's newest hospital in northwest Columbia officially opened in mid-March - just in time to serve as the stunning, if unconventional, backdrop for a few prom pictures. This $120.6 million gleaming glass complex offers the latest example of a national trend that's already hit the Lowcountry. New hospitals resemble four-star hotels.
