Call

The St George's flag was hoisted at The Minster today, legally compliant with the diocesan arms displayed mast-side in the top corner.

The church has arranged a climate protest march this Saturday which ends at The Minster. Extinction Rebellion are also participating, and hopefully me too.

Perhaps the flag is a call to arms for COP and the march?

Competition
Although the building appears to be regular, there are many differences in the fine detail of this shot. How many can you see? Can you also see the flying buttress?

 Elsewhere on the building they are less subtle but still easily missed.
