Mas de Sant Antoni is located on the foothills of the Montsant cliffs, near Morera de Montsant. You can get there by following the path past the Carthusian monastery of Scala Dei towards the main massif, passing by a house called La Pietat, formerly used by monks who needed to rest.
The farm has its origins in an ancient chapel in the village of Montalt, which no longer exists. According to legend, the Carthusian monks were concerned about the proximity of the village to their monastery, so shortly after his arrival in the early 13th century the prior offered the residents fertile lands further afield and generous dowries for the unmarried daughters to leave the village . Historically, the village disappeared at the beginning of the 15th century. In later years, the farmstead is documented as a Carthusian farm. Remains of the chapel dedicated to Saint Anton can still be seen.
