Britain's Prince Charles and his wife, Camilla, toured monuments and wowed Washington tourists on Wednesday on the first full day of their four-day U.S. goodwill tour.

The Prince of Wales and the Duchess of Cornwall were swarmed by delighted tourists and school groups when they arrived to visit the white-columned Lincoln Memorial and worked the crowd with handshakes and hellos.

The 66-year-old heir to the British throne and the duchess spent about 10 minutes inside the memorial as a guide explained aspects of Lincoln's statue and how schoolchildren memorize the addresses carved on the walls.
