But the white structures which have stood for 80 years will now be reduced to rubble. Former England captain Ray Clemence and architect Lord Foster attended a ceremony to mark the end of the famous twin towers. "There was something unique about the stadium itself," said Clemence. "As an England coach, I know how exciting it is for the team to know that in a few years' time, they will be playing here again." The tops of the towers will be kept in storage until the new stadium is completed and will eventually feature in a Wembley Hall of Fame museum at the new ground.

Wembley ushers in new era as towers fall : 7 February 2003

The concrete that fell today, and that will continue to fall from the towers over the next week, will serve a variety of purposes. One lorry load will be stored before it is worked into a statue of a Wembley legend to stand outside the new stadium. The rest will be used in the foundations of the new stadium, ensuring that the Twin Towers are part of Wembleys future as well as its past. Similarly the flag poles from the top of the towers will stand in the new stadiums memorial garden.
