According to their website, La Miroiterie is the oldest artists’ squat in Paris. Located at 88 rue de Ménilmontant in the 20th arrondissement (metro Ménilmontant or Jourdain), it is home to a group of ten artists and musicians who hail from corners of the world such as France, Japan, Guatemala, Brazil and Morocco. The space is intended for social and artistic experimentation, some of which can be admired at the gallery, open 5:30-8:30 pm everyday except Monday and Tuesday.
A jam session is organized every Sunday night, and is usually punk, hardcore or “noise” music. When I visited the place with some other teaching assistants, we lucked out with jazz.
In the summertime, there is a lively atmosphere outdoors as well. BYOB and expect an eclectic crowd.
