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. (Read more Princess Diana stories.)
