Charterhouse of Porta Coeli Monument · Serra, El Camp de Túria, Valencia The Cartuja de Porta Coeli is a Carthusian monastery founded in the 13th century, between 1272 and 1274, in the valley of Lullén, within the municipal district of Serra, on the initiative of Andreu d'Albalat, a Dominican and third bishop of the diocese of Valencia and confidant of King James I, who laid the first stone. Situated at the foot of the Penyes Altes and els Rebalsadors, in the Sierra Calderona, on land where three Morisco villages had previously stood, it received its first community, two monks and six lay brothers, coming from the charterhouse of Scala Dei; its name, meaning gate of heaven, refers to a passage in Genesis. It is the only charterhouse among those founded in the former Kingdom of Valencia that remains inhabited, and it preserves cloisters, a church and a historic scriptorium.
