Planned Extension of the Cite des Congres

An extension project for the Cite des congres was announced by Nantes Metropole president Johanna Rolland during a New Year's wishes speech. The plan called for enlarging the complex toward quai Magellan through a call for tenders issued by Nantes Metropole. The proposed extension included the creation of a hall with 1,700 seats, with construction expected to begin in 2023 and opening planned for 2026. The estimated cost of the project was 55 million euros. The extension had initially been targeted for 2022, but it was suspended after an agreement reached between the two rounds of the 2020 municipal elections.
