There's a few secondhand clothes stores in Paris, but always immaculately selected, expensive and fashionable. Guerrisol however is a huge, dirt cheap jumble sale. Stock seems to rotate daily in each of their four stores, and prices fluctuate on the hour. Sifting through endless rails of synthetic jackets at €3 can suddenly reveal a hidden gem.

Bookstore focused on architecture / landscape / photography / art books

The gallery and bookshop never disappoint a curious mind, but the café is worth the trip alone.

A small market open Tuesday to Saturday in a beautiful hall at 39, rue de Bretagne in the 3rd arrondissement. People come here for lunch as much as for shopping. It is the oldest market in Paris and it takes its name from an orphanage, established in the sixteenth century, who collected the lost children and wore red. Especially the Japanese cookshop and the Cous-Cous are worth going there.

Architecturally stunning, a beautiful and harmonious space showcasing contemporary art. I've often seen some amazing work here and been introduced to new artists making great work. There is a beautiful outdoor space, with installations by Agnes Varda.
