Dave Myers is in Clifton, one of Bristol's oldest and most affluent suburbs, to visit the Grade II-listed Clifton Catholic Cathedral. Built in the 1970s, this example of Brutalist architecture has been plagued with leaks since it opened. It is now undergoing a £1.9 million renovation project, and Dave helps to remove and replace the worn-out lead on the roof.He gets an architectural insight from one of the members of the original design team and finds out what happened to the Pro-Cathedral it replaced. Away from the restoration work, Dave gains a bird's-eye view of one of the most famous suspension bridges in the world.
