Rome's mayor is promoting the use of existing venues in the city's bid for the 2024 Olympics.
Ignazio Marino took part in a daylong seminar at IOC headquarters Thursday as part of the new invitation phase for potential host cities.
Rome is planning to use many of the facilities that were built for the 1960 Games in the Italian capital, including the Foro Italico complex that contains the Olympic Stadium.
Marino says: ''We are not going to overbuild. We are going to develop what already exists.''
The Rome delegation also included Italian cabinet undersecretary Claudio de Vincenti and Rome bid committee general director Claudia Bugno.
Hamburg, Boston, Paris and Budapest have also announced bids for 2024. The IOC will select the host city in 2017.
