These fantastic panels are in the chapel / quiet room of Castlefield Hotel in Manchester. Does anyone know who made them? They are not that old but amazingly nobody at the hotel knew anything about them. You can see them here.
I have finally found out who made these stunning panels: Martin Donlin. It was the very first window Martin had installed in a public place. You can see more of how Martin's work has evolved over the years on his website here.
