Once a marketplace, now the national theatre.
The imposing iron and glass façade of La Criée ("the Auction House") harbours the old interior of the 1909 fish market, and is now also home to the National Theatre of Marseille, which if you're culturally minded can be a marvelous option while visiting this city. La Criée offers a wide variety of ballet, concerts, plays, world music festivals, contemporary dance, children's theatre, and more - we'd suggest you consult its website the moment you know the dates of your stay if you want to make sure you secure tickets. The theatre is quite close to the Vieux Port, in the Rue Rive Neuve, surrounded by restaurants and cafés offering all manner of excellent post-theatre dinner options.
