The countdown to Princess Charlotte‘s royal christening has begun!

The church — which is located at Queen Elizabeth‘s Sandringham estate in Norfolk, England — is also where William’s late mother, Princess Diana, and his cousin Princess Eugenie were christened.

“The Duke and Duchess are hugely grateful for the warm wishes they have received since Princess Charlotte’s birth — many of them from local people in Norfolk — and are delighted the paddock can be opened on the day of the christening,” a Kensington Palace spokesperson said in a statement, referring to William and Kate’s appearance outside the church before the event.

Guests expected to be at the lavish affair include the Queen, her husband, Prince Philip, and Charlotte’s grandparents, Prince Charles, Camilla, Duchess of Cornwall, Carole Middleton and Michael Middleton. Of course, her parents and big brother, Prince George, 23 months, will also be in attendance!

For the occasion, Charlotte will likely wear the royal family’s traditional christening gown, which was designed by the Queen’s assistant and a team of dressmakers at Buckingham Palace. The design of the garment is reportedly based on a christening gown commissioned by Queen Victoria in the 19th century.
