Charterhouse of Escaladei Monument · la Morera de Montsant, Priorat, Tarragona The Charterhouse of Santa María de Escaladei, founded in 1194 by King Alfonso the Chaste, was the first Carthusian monastery on the Iberian Peninsula, from which the other Catalan charterhouses arose, and its domains shaped the historic territory of Priorat. It is located in the village of Escaladei, in the municipal area of la Morera de Montsant, at the foot of the Sierra de Montsant. Its first monks came from the charterhouse of Verne, in Provence; they settled first in the hermitage of Santa María de Poboleda, until around 1203, thanks to donations from King Pedro the Catholic and Queen Sancha of Castile, they were established in the desert of the Vall de l'Oliver. The works, including the main cloister and the first twelve cells, were not completed until 1228. In 1217 Pope Honorius III confirmed its possessions.
