Building the city of peace | Greenbelt 2004 Sanctuary invite us to build a city for God using the craft materials they have provided. They put in a few buildings, roads, pieces of landscape and cars to get it started, and then left it to Greenbelters of all ages to fill in. The Angel of the North, Delirious, Freddie Mercury!! A golden mountain... ...even a sea with surfers. People were invited to take polaroids of what they had made and explain it.
