Frogmore House
After the post-ceremony luncheon, only about 200 of the couple's nearest and dearest were invited to the private wedding reception hosted by the groom's father at Frogmore House. The 17th-century English country home beloved by Prince Charles is located on the grounds of Windsor Castle's home park and is open to the public only three days per year. Obviously, this was not one of those days.
