Avignon 2004: a memorable symposium for fib.

The article focuses on the 2004 fib Symposium on Concrete Structures: The Challenge of Creativity, held from April 26-28, 2004 in Avignon, France. The event combined a magnificent, historically rich venue--the fourteenth century Popes' Palace in the heart of Avignon's old town; over 100 papers and keynote addresses; an excellent level of organisation and coordination of the entire event; and a number of interesting and highly relevant technical visits, including high-speed railway structures and the well-known Millau Viaduct. The closing session looked back on the three days of conference and exchanges and reflected on lessons learned, innovations discovered, challenges ahead for today's engineers.
