Royal reunion: Prince Philip returns to Windsor Castle with Queen Elizabeth ahead of 73rd anniversary

Prince Philip returned to the Windsor Castle alongside Queen Elizabeth just in time for the celebrations of their 73rd wedding anniversary. 

The couple was spent quality time together at Sandringham over the weekend before returning to the Windsor Castle. 

According to a royal insider cited by PEOPLE, the couple will be celebrating the 73rd year of their marriage, after tying the knot on November 20, 1947. 

Earlier in October, the Duke of Edinburgh stayed back in Norfolk while the monarch made her way to the castle to resume royal duties amid the COVID-19 pandemic.

While England will soon have its second lockdown in place, Prince Philip and Queen Elizabeth always planned on returning to the castle together.

The pandemic has given ample time for the Queen and her husband to spend time together.

The couple had spent their first lockdown in Windsor, before heading to Balmoral estate in Scotland to vacation over the summers.

Meanwhile, the monarch has been shouldering her royal duties from the Windsor Castle only.

 It was the Queen's intention to travel into London to Buckingham Palace for "selected audiences and engagements," the source said.
