Three days preceding Lent, an atmosphere of merry industriousness pervades the town as thousands of Binchois produce lavish costumes and participate in drum rehearsals and themed balls. On Shrove Sunday, which marks the official beginning of the carnival, Binche’s streets and cafés come alive with roving hordes of masqueraded merrymakers. The Mam’selles, men dressed in extravagant female attire, are particularly prominent on this day. The carnival culminates on Mardi Gras.
