King Charles III crowned at London's Westminster Abbey

King Charles III was crowned Saturday at Westminster Abbey.

Trumpets sounded inside the medieval abbey and the congregation shouted “God save King Charles” as the ceremony began in front of more than 2,000 guests, including world leaders, aristocrats and celebrities. Outside, thousands of troops, tens of thousands of spectators and a smattering of protesters converged along a route that the king traveled from Buckingham Palace in a gilt-trimmed, horse-drawn carriage.
