Economy On the border of Raincy, old quarries where gypsum was removed since the seventeenth century are still visible. The exploitation of fine plaster, known as "Paris", was the main Gabonese industry until the 1950s. The old Mussat quarries closed down in 1965. By the end of the nineteenth century, in certain abandoned quarries, mushrooms were already being grown in Paris. The former gypsum quarries of Gagny were replaced by a large shopping centre project, which itself was replaced by the wood of the star, a plantation of trees.
