WINDSOR, England - Prince Charles and Camilla Parker Bowles were married Saturday at the 17th century Guildhall, capping a decades-long love affair that lasted through the prince's first marriage to Princess Diana.

The couple emerged from Guildhall to the cheers of onlookers and a jazz band playing, "Congratulations." They drove to Windsor Castle in a Rolls-Royce for a blessing ceremony at St. George's Chapel to be attended by Charles' mother, Queen Elizabeth II, and conducted by Archbishop of Canterbury Rowan Williams.

Many of the wedding guests, including Charles' sons William and Harry, were driven to the wedding in a rented bus. Parker Bowles' ex-husband, Andrew, also was among the fewer than 30 guests at the civil ceremony.

The bride wore an oyster silk basketweave coat with a herringbone stitch and a matching chiffon dress. She also wore a matching straw and lace hat with feather details.

Charles, in contrast to the military uniform he wore for his first wedding to Diana, was dressed in formal morning wear.

The hall was lined with Jasmine and Lily of the Valley - known to symbolize the return of happiness.

Waving Union Jack flags or raising banners honoring Diana, crowds lining the streets of the handsome riverside town of Windsor waited in chilly sunshine for the nuptials, which were postponed so Charles could attend Friday's funeral of Pope John Paul II in Rome.

"It's up to him who he marries," said Barbara Murray, 41, who camped overnight with her two daughters to stake out a vantage point to see the couple. "Whoever he chose wouldn't be the same as Diana."

Nearly eight years after Diana's death, some have bridled at accepting Camilla Parker Bowles as a future queen, seeing her relationship with Charles as the reason his first marriage fell apart.

"She broke up their marriage," said Yvonne Williams, 67, who raised a banner that read: "Long live the Queen, Diana Forever: King Charles, Queen Camilla - Never."

Security was very tight. In addition to sharpshooters on rooftops, plainclothes officers moved around in the crowd, dogs sniffed for bombs, and normally unarmed police carried handguns in the streets around Windsor Castle.

Thames Valley Police, responsible for security outside the castle, had 550 officers on duty and Scotland Yard, which is in charge inside the castle, had dozens more.

Parker Bowles technically will be the Princess of Wales - a title she wishes to avoid using, in deference to memories of Diana. Instead, she will be known as the Duchess of Cornwall.

When Charles takes the throne, Parker Bowles legally will be queen, but she wishes to be known as Princess Consort - a bow to opinion polls that show 70 percent of the population opposed to Queen Camilla.

In keeping with tradition, Parker Bowles spent Friday night at Clarence House, the London residence of the Prince of Wales, while Prince Charles spent the night at his country mansion in Gloucestershire, with his sons Princes William and Harry.
