CHÂTELAIS
I'm not certain which specific event you're referring to, as "Châtelais" is best known as a small commune (former commune) in the Maine-et-Loire department of France, which merged into the new commune of Erdre-en-Anjou in 2016. If you can provide more context—such as where you saw this event listed or what kind of event it is—I'd be happy to help write a summary.
