The service for the little royal will be held on July 5, at St. Mary Magdalene's Church on Queen Elizabeth II's Sandringham estate, Kensington Palace said in a statement to PEOPLE on Friday.
It is on the Queen's vast estate in Norfolk that Prince William and Princess Kate have their 10-bedroom home, Anmer Hall. William's mother Diana was born at Park House, which is also on the Sandringham estate.
Charlotte will follow in the footsteps of Princess Eugenie, 25, whose ceremony was also held there.
While St. Mary Magdalene Church was one of the places being mulled over for the service, what was never in doubt is that Charlotte, like brother Prince George and other royal children, will be dressed in a family heirloom. The one-month-old is expected to be christened in the traditional christening gown, which was designed by the Queen's assistant, Angela Kelly, and Buckingham Palace's team of dressmakers in 2008 and based on a christening gown commissioned by Queen Victoria in the 19th century.

The royals will also take the famous Lily Font with them for the service.
The palace confirmed the ceremony will be conducted by the Archbishop of Canterbury, the Most Reverend Justin Welby, who baptized Prince George in October 2013. It will be private, but it's expected portraits, like those taken of smiling George and his family, will be released to the public afterwards.
