 After years of criticism for its state of neglect, Princess Diana's family is finally renovating the beloved royal's gravesite at their home. Her brother, Earl Spencer, will lead the first major changes to Althorp Estate in 350 years, in advance of the 20th anniversary of her death.

 The Princess, who died on August 31, 1997 at the age of 36, is interred there on a small island. Her final resting place features a modest temple, along with another commemorative statue at the entrance of the grounds.

 Two years ago, the Princess's former chef accused her brother of allowing the gravesite to fall into disrepair. He claimed the overgrown vegetation and algae-filled pond disgraced her legacy — not to mention a long-running exhibit that charged visitors to look at Diana's belongings. While the museum is now closed, guests can still tour the property in the summer months for about $25 apiece.

 "The island where the late Princess is buried has always had a full growth of mature trees...which intentionally lends privacy to the Princess's final resting place," a spokesman for the estate later responded. "The Temple is maintained and assessed on an annual basis."

 This year, it seems, the assessment called for bigger changes. While the family has not revealed specific plans, Versailles' principal gardener designed the original 500-acre park more than three centuries ago. After Diana's death, 36 oak trees (one for each year of her life) along with hundreds of white roses and water lilies were planted in her honor.

 The island where Diana, Princess of Wales is buried is to receive a multi-million facelift as part of the Spencer family estate gardens’ first major revamp in 350 years. 
 
 A statement on the Althorp website describes the “ambitious” project, which will be overseen by Earl Spencer’s third wife, Lady Karen, whom he married in 2011. 
 
 It will include an “extensive redesign” of the Oval Lake, where she was laid to rest in 1997, to “honour her memory”. 
 
 It follows criticisms from her former personal chef, Darren McGrady, that her burial place had become neglected. 
 
 He visited the 500-year-old estate, which has been home to the Spencer family for 18 generations, in August 2014, and posted a number of pictures of a moss-covered memorial to the princess on Twitter. 

 Redesign of The Oval Lake Marks Initial Stage of Garden Project at Althorp, the Spencer Family’s historic English Estate, in the First Major Revamp of the Gardens in 350 Years 
 
 The Oval Lake where Diana, Princess of Wales, was laid to rest on September 6, 1997, is undergoing an extensive redesign to honour her memory. It will be completed in time for the 20th anniversary of her death, in August 2017. 
 
 The island is located at the centre of the Spencer family’s 500-year-old ancestral estate, Althorp, which spans 13,000 acres surrounding its walled 500-acre park. Althorp, located 70 miles from London in Northamptonshire, England, has been the Spencers’ historic home for the past 18 generations, since it was built in 1508. The island at Althorp is in the process of undergoing remodeling, along with other parts of Althorp’s gardens. 
 
 The ambitious project at Althorp, which Earl Spencer’s wife, Countess Spencer is leading, will constitute the first transformation of the historic grounds since they were originally designed 350 years ago by André Le Nôtre – King Louis XIV of France’s principal gardener who masterminded the gardens of Versailles. 
 
 While Althorp is open to the public in July, August and at other select times during the year, there is no public access to the island itself.
– As the 20th anniversary of Princess Diana's 1997 death approaches, the family estate where she's interred is gearing up for its first makeover in 350 years, the Telegraph reports. The New York Daily News in 2014 reported on a series of tweets unleashed by Diana's former chef, Darren McGrady, who accused her younger brother, Earl Spencer, of neglecting her gravesite at the Althorp Estate. McGrady shared a photo showing algae covering the lake that surrounds an island memorial to the late princess. A spokesman for the estate said, per the Telegraph, that the grave had become "part of the ancient landscape over time" and the overgrown plants around the memorial temple "lend privacy to the Princess's final resting place." Still, the planned multimillion dollar revamp, to be overseen by the earl's third wife, will include an "extensive redesign" of the lake to "honor" Diana's memory, per a press release on the website for the estate, the Spencer family home since 1508. The release notes the overhaul "will constitute the first transformation of the historic grounds since they were originally designed 350 years ago by Andre Le Notre—King Louis XIV of France's principal gardener who masterminded the gardens of Versailles." Althorp is open to visitors, House Beautiful notes, who can pay about $25 to tour the 13,000-acre property in July and August. Tourists, however, are not permitted on the island that holds Diana's grave. Last week, Prince Harry spoke openly about his mother's passing.
