The 14th-century Vozmediano Castle is located atop great hills on the border with Aragon. Throughout the structure you can see various construction styles from different periods; Roman surrounding walls, a Muslim watchtower and medieval walls with battlement hexes.
The castle is currently in ruins although it was made up of a double walled enclosure, the outer walls being strengthened on the most vulnerable corner by a great quadrangular tower where there was an access gate, and on the other corner, a circular tower that was built later on. Another quadrangular tower placed in the middle of the wall was used as an abutment, and the rest of the perimeter does not contain any more towers and is actually much thinner than the other walls. The inner enclosure still maintains the original keep and is currently being used as the village’s cemetery. “Marqués de Santillana” dedicates some verses to this area where the Queiles River’s source is located in the foothills of Mount Moncayo.
References:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
