Monastery of Piedra Monument · Nuévalos, Comunidad de Calatayud, Zaragoza The Monasterio de Piedra, dedicated to Santa María la Blanca, was founded in 1194 by thirteen Cistercian monks who came from Poblet and settled beside the Piedra river on the site of the old castle of Piedra Vieja. It was abandoned in 1835 with the Mendizábal disentailment and, bought five years later by a private individual, was converted into a tourist establishment; it was listed as a Monumento Nacional in 1983. Its construction took place in three stages — the primitive Gothic of the 13th century, the Renaissance Gothic of the 16th, and the classical-baroque of the 18th — and the walled precinct is entered through the medieval keep tower (torre del homenaje). Notable features include the cloister with its large pointed arches and capitals with foliage carving of Byzantine inspiration, and the main staircase, which unfolds in two flights beneath a vault.
