The younger brother of Princess Diana, Charles Spencer, the 9th Earl Spencer, has been serving free meals for the NHS frontliners in this pandemic. He recently shared that they sent out their 7,500th meal as prepared in his kitchen at the Althorp House.

In a post on Instagram, the Earl Spencer said that they have volunteers coming to his home since April 18 to prepare the food for the frontliners. He shared the photos of some of these volunteers, who are actually kitchen staffers and the chef, Danny Tompkins.

"Last week a local doctor came up to me (at a suitable distance, of course!) to say how, after 5 hours in surgery, she realized she had no food to go home to," the Earl Spencer shared. "But a colleague told her that Danny's food was available to her. 'And it's so incredibly tasty,'" he proudly wrote, while thanking the chef and his team. 

In an interview with Fox News, the Earl Spencer said that they aimed to feed 250 NHS workers every day. They also received several donations of food supplies and containers from the local community. 

Princess Diana's brother partnered with Food4Heroes for this initiative. The meals are part of a rolling menu that includes shepherd's pie, chili and some vegetarian choices.

The Earl Spencer has been staying in isolation at the Althorp House with his wife and youngest daughter Lady Charlotte Diana. The house, built by the Spencer ancestors in 1508, has 90 rooms and sits in a 550-acre land. 

Princess Diana's childhood home is usually open for tourists. However, it's unclear if the estate will open for the summer amid the coronavirus crisis.

The Earl Spencer said that the Althorp House receives an average of 20,000 tourists every year. Part of the tour includes paying respects to his deceased sister at her burial site in the estate. 

Princess Diana's resting place is in a small island at the lake inside the vast property. However, visitors can't go to the island itself as it is a private family sanctuary full of trees planted by Princess Diana and her sons, Prince William and Prince Harry.

When Princess Diana died in August 1997, thousands of people flocked the London streets to see her casket for the funeral rites. However, the actual ceremony at the Althorp House was kept private for the family. Only a handful of people were present at her burial -- Prince Charles, Prince William, Prince Harry, Princess Diana's siblings, her mother and a few of her closest friends.
