Welcome to Then and Now, where we compare images of Merseyside streets, landmarks and buildings from bygone days with how they look today.

Our striking main image this week shows sunlight streaming through the shell of the Cook Street Arcade after it was devastated by German bombs on May 3rd 1941.

The stark late Spring sun shows the full extent of the destruction. The seven-night bombardment from May 1st involved 681 Luftwaffe aircraft and saw 2,315 high explosive bombs dropped on Merseyside.

Around 120 incendiary bombs also fell on the city and docks, putting 69 out of 144 cargo berths out of action. There were 2,895 casualties.

A high explosive bomb damaged many stained glass windows in Liverpool Cathedral while another landed on the front steps without detonating.

More than 6,500 homes were destroyed over the seven days of raids and a further 190,000 were severely damaged. Around 70,000 people were left homeless. More than 400 fires were tackled by the fire brigade overnight on May 3rd alone.

At the height of the May Blitz, 9,000 workers from outside Liverpool along with 2,700 soldiers were drafted in to clear debris and make buildings safe.

Cook Street today presents a more peaceful picture. It is renowned for its imposing architecture, including the world’s second glass curtain walled building designed by Peter Ellis in 1886.

No 6. Cook Street boasts floor-to-ceiling glass that allows light to penetrate deep into the building, presenting a contrast to the surrounding Victorian buildings.
