Big Air Package: The Largest Inflated Envelope in History by Christo

Big Air Package is the latest project from artist Christo installed at the Gasometer Oberhausen in Germany, a facility that still holds the record as the largest disc-type gas holder in Europe that was converted into an exhibition hall in the 1990s. Big Air Package is the largest ever inflated envelope without aid of a skeleton (Gasometer Oberhausen bills it as the largest indoor sculpture in history) and reaches 90 meters high, with a diameter of 50 meters and a volume of 177,000 cubic meters. — thisiscolossal.com
