The island where Princess Diana was laid to rest is undergoing extensive renovation work, it has been revealed.

It will  be completed by August 2017 – in time to mark the 20th anniversary of the Princess of Wales’ death.

Princess Diana was laid to rest on an island at the centre of the Althorp Estate, a stately home set within a 13,000-acre estate in Northampton owned by the Spencer family.

The island lies at the centre of the estate’s Round Oval Lake, and features a number of trees and vegetation along with a monument commemorating the late Princess. Following Diana’s death in August 1997, an oak tree was planted to mark each year of her life, along with hundreds of white water lilies and roses.

There is also a temple for visitors to pay their respects, which features Diana’s name engraved on the top.
