The Prince of Wales has visited a Second World War air raid shelter as part of a project marking his 70th birthday.
Prince Charles visited Coventry's Drapers' Hall to learn more about a multi-million-pound project to transform the 19th-century building into a music venue and education centre for young musicians.
He was taken on a tour of the Grade II* building begun in the 1830s but empty for the past 30 years, and ventured into a basement to see a rusting Victorian range and a Second World War air raid shelter.
It survived the Second World War bombing despite being a few metres from Coventry's cathedral, which was destroyed.
Geoff Willcocks, vice chairman of Historic Coventry Trust, said: "I was down in the cellars with the prince and one of the things he was saying was it was incredible that the building was still standing despite what had happened to Coventry in the Blitz.
"The cellars were quite a spectacular moment because, obviously the paint's peeling and it's a bit rough, but it's like stepping back in time."
