Bridge of Aspiration, Royal Opera House, London

Decorative, functional and highly symbolic, the Bridge of Aspiration by WIlkinson Eyre Architects links the Royal Ballet School to the Royal Opera House. It’s literally the access point for ballerinas to enter the Opera House for a performance. It’s made of ‘a concertina of 23 square portals with glazed intervals’ rotating in sequence to skew in alignment, performing an appropriately graceful quarter-turn along the length of the bridge.
