In celebration of Princess Diana's 20th death anniversary, her sons Prince William and Prince Harry will build a specially made statue for their late mother. The sculpture will be built outside the royal family's home in London - the Kensington Palace.

"It has been 20 years since our mother's death and the time is right to recognize her positive impact in the UK and around the world with a permanent statue," the husband of Kate Middleton said in a statement. "Our mother touched so many lives. We hope the statue will help all those who visit Kensington Palace to reflect on her life and her legacy."

Princess Diana died in a car crash in August 1998. That time, Prince William and Prince Harry were only 15 and 12 years old. According to ABC News, the statue will begin to be built soon and expected to be seen in the public at the end of 2017.

To recall, the first permanent memorial for the first wife of Prince Charles was a 210-metre long fountain and was unveiled in the Hyde Park in 2004. It even went to a lot of ceremonial issues and design problems. In fact, it was even closed down for a number of times as a board of politicians said it was "ill-conceived and ill-executed."

Meanwhile, in an interview with Hello, Prince Harry said he and his older brother Prince William agreed to build a "permanent memorial" for their late mother, Princess Diana. The 32-year-old Prince Henry of Wales wanted to be assured that there is something that will make everyone remember the former Princess of Wales.

He, too, noticed that there is nothing in London or anywhere in the UK where his mom can be remembered. Hence, he perfectly thinks that he, his brother and some people will definitely agree to work on something that could bring her memories back.
