Queen Elizabeth has embarked on an emotional trip.

Today, the Queen flew by helicopter from Windsor to Sandringham ahead of a meaningful anniversary. She'll stay there through Feb. 6, which marks 70 years since her father King George VI's death.

Queen Elizabeth leaves Windsor on emotional trip

Of course, the day also represents when Queen Elizabeth ascended the throne. Her father passed away on Feb. 6, 1952, so the day — also called Accession Day — will mark her 70th year as ruler.

Those milestones are no doubt emotional, but there's more. On the Sandringham estate, the 95-year-old Queen will stay at Wood Farm, according to the Daily Mail.

It'll be the first time she stays there without her husband Prince Philip. He spent his final years at Wood Farm, and it was known to be one of his favourite places.

Tributes left at Wood Farm after Prince Philip's death in 2021.

Prince Philip died at the age of 99 last year and had been married to the Queen for 73 years.

She was seen visiting Wood Farm shortly after his death, but she'll now move in there for a few weeks. Windsor Castle has been her primary residence amid the pandemic.

So it should be a solemn trip for the Queen. At the same time, she will make history on Feb. 6. She is the UK's first monarch to ever reach 70 years on the throne.

The country will mark the Queen's 70th anniversary with various festivities this summer.

For the rare Platinum Jubilee, the Queen could even welcome her grandson Prince Harry back to the UK.
