RON ARAD: Grand Square is probably the most difficult site in Jerusalem. It's a place that suffered some suicide bombing. It's a place crack dealer’s favor. And it's a place that was never lucky with its design or its public art. When I was approached, the last thing I wanted to do was a piece of sculpture on a pedestal. So I started playing with bundled cones pointing to the center of the Earth then I can get like a perforated canopy. But then it looked too biological, which was the last thing I wanted.
Later, struggling with it, I remembered that the British mandate left a law in Jerusalem that you're only allowed to build in stone and Israelis never bothered changing the law. So I thought I won't build it out of stone but I'll take stone patterns as the source. As the sun moves above it, it casts a shadow on the floor that looks like a moving shadow of a stone building pattern. And it's different in different seasons.
