The new Prince, baby George, was christened just as the Sun entered Scorpio on October 23, 2013, in the private Chapel Royal at St James Palace.
The Sun at 0 Scorpio activates 0 degrees of all the fixed signs (Taurus, Leo, Scorpio, Aquarius). This is significant as these are family points for the British Royals. Queen Elizabeth II has the Sun at 0 Taurus, Prince Charles has the Moon at 0 Taurus and Prince William has Jupiter at 0 Scorpio.
At the christening, the Sun was on William's Jupiter-MC conjunction, suggesting this day highlighted the link between baby Prince George and William's "career". As heir to the throne, one of William's most important jobs is to keep the line of succession going, and to provide further heirs.
The birth of Prince George is important to William fulfilling his royal duties -- at the most basic level. The activation of Jupiter in William's chart at the time of George's christening speaks to the joy of William in publicly presenting his son George for his official naming.
Jupiter itself was in the family-friendly sign of Cancer at the christening, highlighting the joy of family events. Jupiter activated Kate's karmic point, the North Node, (which happens to align with Queen Elizabeth's North Node) providing clues as to how her role as mother of Prince George aligns with her personal destiny. This was a lucky and fortuitous cycle for Kate -- and for the Queen, as she witnessed the christening of her great-grandson.
The christening occurred while Mercury was retrograde, so there were some delays. Other major events occurring under Mercury Retrograde required starting over, so follow-up after the fact was required.
Venus in Sagittarius, and the Moon in Gemini, formed an opposition at the christening. This was a telling alignment as it highlighted the tension between private family events and public duties. William and Kate's choice of venue -- the smaller and personally meaningful Chapel Royal at St James Palace -- suggested their focus was on family and tradition. (This is where Diana's coffin rested before her funeral.) They couldn't, however, avoid the fact the public had great interest in their son's special day.
And for Prince George himself? At his christening, Saturn in Scorpio aligned with his North Node (also in Scorpio), showing that his christening was the first step to him fulfilling his life purpose. His future role as King of England requires him to belong to the Church of England, a process that begins with his christening. This event was about the baby Prince being supported by his family to create the foundation he needs for his future.
The venue and date spoke to family and past connections, which is no surprise as William (a Cancer) and Kate (a Capricorn) value honoring tradition above all else.
