“On Tuesday, Prince Charles held a garden party for his 70th Birthday Patronage Celebration at Buckingham Palace in London,” Time reported.

Prince Charles was actually born on November 14, “but because this is a milestone birthday for the royal family’s next in line to the throne, there are a series of celebrations in his honor throughout the year,” according to People.

In the video, guests who attended Prince Charles’ 70th birthday celebration are seen outside Buckingham Palace waiting to catch their rides back home.
