A highly anticipated exhibition at America’s most famous prison by one of China’s most prolific contemporary artists will open to the public Saturday, September 27.

Chinese dissident artist and architect Ai Weiwei's major installation @Large opens this weekend inside the former prison building of Alcatraz Island in San Francisco Bay.

The big man of Beijing's new show fills the former prison with a giant rainbow dragon and Lego models of 175 prisoners of conscience, from Nelson Mandela to Edward Snowden. The artist's bravery and commitment are extraordinary

Alcatraz is undergoing a big change. The former prison which was home to Machine Gun Kelly and Al Capone is now hosting what many say is the most anticipated contemporary art show of the year.

The exhibit is called ‘(at) large: Ai Weiwei on Alcatraz’ and opens Saturday at the former maximum-security prison. Admittance is free. The artist directed the installation of the exhibit while under house arrest in China for what supporters say are trumped-up tax charges.
