Indians, Pakistanis, Sri Lankans... in France; there may be more than 100 thousand of them, the majority in Paris. Their activities are mostly to be found in the 10th arrondissement: one often refers to "Little India". There is a small concentration of restaurants, barbershops and Bollywood DVD sellers at Passage Brady, which I already posted about, obviously dominated by Pakistanis. Further north, especially along Rue due Faubourg St. Denis, you will find an even higher number of establishments, obviously more dominated by Indians and Sri Lankans. This is also the area where you can find what seems to be the only Hindu Temple in France, the "Temple Ganesha", or "Sri Manika Vinayakar Alayam". You can find it 72, rue Philippe de Girard.
Hinduism is of course the dominating Indian religion, followed by Islam. Ganesha (or Ganesh, Ganapati, Vinayaka, Pillayar) is one of the major Hindu Gods, the Elephant God, revered as the Remover of Obstacles, patron of art and sciences and the "Deva" (the Sanskrit word for a god or deity) of intellect and wisdom.
The Paris temple is very modest, occupying what obviously previously was a restaurant kitchen, created on the personal initiative by a Mr. Sanderasekaram in 1985. You are welcome to visit (if you take off your shoes). You may even kindly be offered some vegetarian food!
