A city centre building many walk past every day is still surprising visitors with what it means.
But as many people walk past the former Yates's pub every day, people are still learning what the giant circle means. It has recently gained much interest on social media as questions were asked on what it was and why it was there.
Posting on Reddit recently, one social media user wrote: "How did the giant circle on the building on Moorfields come about? It’s like someone used a laser cutter like in Mission Impossible, but mega size!"
