Both Bastille and Popincourt open-air markets are big and popular. They are located on the same street (Boulevard Richard Lenoir), and in the same area, the 11th. Their alleys are broad and so are the stalls! The well-presented fresh food is appealing and the vendors are quite friendly.
They are complementary because not open on the same days.
Marché Bastille: open thursday from 7.00 a.m. to 2.30 p.m. and sunday from 7.00 a.m. to 3.00 p.m.
Marché Popincourt: open tuesday and friday from 7.00 a.m. to 2.30 p.m.
