Radio 2 building renamed in honour of broadcasting legend Sir Terry Wogan
Sir Terry Wogan has been honoured at the location where he spent so many "happy years" hosting his Radio 2 show - with the building now named after him.
BBC Western House in central London, home to Radio 2, has been renamed BBC Wogan House.
His family attended the inauguration of Wogan House, where the new architectural signage was unveiled.
BBC deputy director-general Anne Bulford and director of radio Bob Shennan were also at the event, which honoured the life and career of the broadcasting star.
The Wogan family described the move as a "wonderful gesture".
"BBC Radio 2 was such an important part of Terry's life," they said. "He spent so many happy years there doing what he loved - chatting and laughing with the listeners from his studio in BBC Western House every weekday morning.
"We are so proud that the building is being renamed Wogan House in his honour, the whole family are extremely touched by such a wonderful gesture."
Mr Shennan said: "Terry was a much-loved Radio 2 personality and it is right we honour him in this way.
"Each time we all walk through the doors of Wogan House we will be forever reminded of him - his warmth, wit and endless charm."
Sir Terry died in January, surrounded by his family, after a battle with cancer.
He hosted his Radio 2 breakfast show from the studios at BBC Wogan House from 1972 to 1984 and from 1993 to 2009, when he signed off for the final time by telling his loyal listeners: "Thank-you for being my friend."
Sir Terry, known for his velvety voice on radio and television, enjoyed a career spanning more than 50 years at the BBC.
As well as his long-running Radio 2 breakfast show, he was also known for his chat shows, Children In Need and his often blistering commentary on the Eurovision Song Contest.
In September, the biggest names in broadcasting paid tribute to him at a packed service at Westminster Abbey.
Fellow broadcaster Chris Evans led the tributes, saying: "He will always be the best."
Lady Wogan told the Press Association her late husband would be delighted that the building has been renamed in his honour.
"He'd be excited and very, very happy because he loved this building, doing his morning programme here for so many years," she said. "It's just wonderful."
She added: "He came here full of the joys of spring every morning.
"I can't think of a nicer tribute than changing the name to Wogan House."
Lady Wogan said the family have been overwhelmed by the tributes paid to the star since his death.
"It's just been amazing, amazing. I never thought it would be like this but it has been overwhelming and fantastic," she said.
"We are very proud as a family of him."
Mr Shennan called the event, which was attended by Sir Terry's children Mark, Alan and Katherine, a "special day".
Before revealing the new sign, he said: "All of us who work in this building remember working with Terry Wogan.
"There's a photo upstairs on the wall of Radio 2 and it's of Terry standing right here, on the morning of his final breakfast show. He's standing addressing a crowd, arms aloft like a prize fighter, acknowledging the crowd with a big smile on his face.
"There were photographers, reporters, camera crews, well-wishers, BBC people, an extraordinary crowd of people on an extraordinary day reflecting on an extraordinary man.
"So today it's such a great privilege for us to be able to unveil a new name for this building where he built the fantastic success of Radio 2.
"It means that any time any of us walk through these doors, we will automatically think of Terry and his charm and we will smile."
Lady Wogan also spoke about this Friday's Children In Need, for so long associated with Sir Terry.
"There are very good presenters doing it so they should do well," she said of the appeal show. "I hope they do."
