Photo: The funeral of Queen Elizabeth II

Britain and the world said their last goodbye to Queen Elizabeth II at a state funeral on Monday that attracted presidents and kings, princes and prime ministers – and crowds that flocked to the streets of London to honor a monarch the whose reign of 70 years defined an age.

An eventful day in London and Windsor began early when the doors of the 900-year-old Westminster Hall were closed to mourners after hundreds of thousands showed up in front of his flag-wrapped coffin. Many had waited for hours in line, even on cold nights, to witness the lie in an outlet of collective pain and respect.
