It is a four-story 350,000 sq ft building built over the corner of the underground Moscone Center convention center. Metreon opened on June 16, 1999, as the first of a proposed chain of Sony "urban entertainment centers", aggregating dining, games, music, exhibitions, shopping, and movies. Sony intended the ambitious US$85 million project to be a theme park and gallery for Sony products, and to reinforce a sophisticated image for the Sony brand.
