Alan Titchmarsh doesn’t want to erase history with ‘Secrets of the National Trust’.
The 70-year-old presenter has insisted the upcoming Channel 5 programme should paint an honest picture of the past without "apologising for things that happened 200 years ago".
Speaking to the Daily Star newspaper, he explained: "One place we visit in the series is Penrhyn castle where they’d made a lot of money in the sugar trade.
"They had about 700 slaves, which is obviously appalling to us now. But you have look at the times."
Alan insisted the show would go beyond simply "houses and gardens", with each National Trust site having its own story to tell.
He added: "It’s about the people who’ve lived in them, the personalities, how they lived, the fascinating stories they tell.
"My role as presenter isn’t to show off my ow knowledge. It’s to open doors for the viewer, open windows and… open minds, really."
The star also suggested the only reason "older people" tend to visit the historical sites more often youngsters is "because they have the time".
Asked if the National Trust’s work is appreciated by all generations, he explained: "I don’t have a downer on the younger generation.
"They’re very bright. They’re aware of custodianship and stewardship, which is what the Trust is all about.
"It does tend to be older people who visit these places because they have the time."
Meanwhile, the English gardener has previously spoken on how his work helps him maintain his youthful appearance.
Speaking last year, he said: "I don’t use any skin products. For me, gardening is the secret to looking good, I can’t believe that I am going to turn 70 next March.
"I walk a lot – I walk every day – and my wife Lynn keeps me on my toes."
