William Henry Barlow's 240-foot single-span roof was the largest enclosed space in the world at its opening. In front, George Gilbert Scott designed the Midland Grand Hotel in red Gripper's brick with soaring Gothic pinnacles. Rescued from demolition in the 1960s by Sir John Betjeman, it stands today as the restored gateway for continental trains.
