The gypsum works of Alameda de la Sagra Curiosity · Alameda de la Sagra, La Sagra, Toledo Image of Alameda de la Sagra, not of the place itself. The gypsum works (yeserías) of Alameda de la Sagra originated in a colony of gypsum workers from neighboring Cobeja who settled there in the 14th century, and gypsum extraction has dominated the local economy ever since. In the 18th century, about forty-three thousand two hundred and sixty cahíces of gypsum were fired each year, the white variety selling at 8 reales and the black at 6.5 reales, generating total revenue of 253,200 reales. The gypsum workers dug with blasting charges and picks weighing eight to nine pounds, and stored the goods in caves, where each seller had to wait their turn at the door before selling.
