French commune, Sinnamary takes place in Guyana, along the river of the same name. It takes its name from the Latin Nihil Sine Maria, meaning Rien sans Marie.
Originally Amerindian, the city was colonized in the second half of the eighteenth century, before becoming a place of deportation for French political prisoners. The theater of a gold rush in the mid-nineteenth century, the town sees the creation of a new penitentiary in the early 1930s dedicated to Indo-Chinese prisoners.
Today, the municipality is best known for its preserved and wild natural heritage.
