In Castilla y León, Spain, on the outskirts of the city of Soria, San Juan de Duero, also known as Arcos de San Juan de Duero, is a collection of Romanesque architecture. What is visible today, including the church, are actually only the remains of a military monastery belonging to the Hospitallers of Saint John of Jerusalem, also known as the Knights of Saint John, which was built at the beginning of the 12th century on the banks of the Duero River and was inhabited until the end of the 18th century.
