Queen Elizabeth II lit up Windsor castle in blue in honor of the National Health Service staff and all other essential workers who are fighting the coronavirus. The Queen is, currently, residing at the royal castle with Prince Philip following the outbreak of COVID-19 in the U.K. and Prince Charles tested positive for the virus. 

The longest-reigning English monarch showed her support and appreciation to all healthcare practitioners in the country who are helping to stop the spread of coronavirus. The country has alredy recorded nearly 34,000 positive COVID-19 cases while deathtoll stands at almost 3,000. 

The lighting up of the Windsor Castle in blue, on Thursday, night coincide with the #ClapForOurCarers campaign to show appreciation to the doctors, nurses, and other essential workers in the country. The second round of the weekly applause saw thousands of people stand on their doorsteps and at their windows at 8 p.m. on Thursday.

According to Reuters, U.K. Prime Minister Boris Johnson also briefly stepped out into Downing Street to join in the applause. Johnson has been tested positive for the virus last week and is currently in self-isolating. The crew of several Royal Navy ships also shared videos of their vessels blowing their horns to join the campaign. 

The Queen isn't the only member of the royal family who showed support for the NHS staff. Last week, Kensington Palace posted a clip of Prince William and Kate Middleton's children clapping outside their home. Prince George, Princess Charlotte, and Prince Louis were filmed clapping from their garden at Anmer Hall.

Prince Charles and Camilla, Duchess of Cornwall, were also recorded clapping at their Birkhall home where they were self-isolating. The Prince of Wales has been earlier diagnosed positive of COVID-19. He has since recovered from the virus.

Meanwhile, the Windsor Castle is not the only landmark in England that lit up in support of medical workers in the country. The top of the Shard, a skyscraper in the London Bridge area, as well as the Gothic exterior of King's College Cambridge were also illuminated in blue, which is the color of the NHS logo.

In addition, the Queen also sent a heartwarming message to the workers who helped build the new NHS Nightingale Hospital in London. It was constructed by 200 military personnel, including an infantry from the First Battalion of The Royal Anglian Regiment. 

The official royal family Twitter account shared a video of showing members of the British Armed Forces working hard on the new hospital. The new medical facility will care for 4,000 coronavirus patients.
