The Pontefract landmark opened its gates to the public for the start of a two-day celebration in the castle, with visitors gathering in the grounds.
One royal visitor, Yvonne Slack, travelled from North Yorkshire to witness the historic event with her friends.
She said: “I’ve come from Malton in Ryedale to watch the Coronation and make memories!
"This hasn’t happened for 70 years, it’s huge, and I want to watch it happen, and have a great day, with some really good friends.”
Pontefract Castle will continue the celebrations tomorrow (Sunday) as the site hosts a ‘Right Royal Day Out,’ an event that features free entertainment and food vendors.
Here are 16 pictures of the crowds and celebrations at Pontefract Castle today.
