Prince William and Prince Harry are helping to keep their late mother's memory alive at their childhood home.

According to [People](http://www.people.com/people/package/article/0,,2039522220994901,00.html)_, William, 34, and Harry, 31, have backed new plans to build a temporary memorial garden for Princess Diana on the Kensington Palace grounds.

The garden proposal comes from Historic Royal Palaces, the charity that runs the public areas of the palace. The new outdoor space is reportedly just one of several initiatives to honor Princess Diana ahead of the 20th anniversary of her 1997 death.
