In Cordoba, the mayors of the candidate cities will be invited to make a short presentation of a maximum of 5 minutes. The presentations will take place in the morning of Wednesday 25 September 2024, and the voting period for the election of the host city will be held during lunch time on Thursday September 26. The name of the host city of the 2026 World Congress will be announced during the last session of the General Assembly, on Friday September 27 in the afternoon. All the mayors interested in submitting the candidacy of their city are invited to complete the following form.

Deadline to submit a candidacy
