First built by the Byzantines, Amantea Castle was strengthened by the Arabs. The current cylindrical tower is however to the Norman-Hohenstaufen age. It was long besieged by Charles of Anjou's troops in 1269. It was nearly destroyed in the earthquakes of 1638 and 1783 and during the French siege in 1806-1807. It is now a public structure, but is abandoned.
Castle, now in ruins, is on plateaux with a beautiful view both on small bay of Oliva river, on Tyrrhenian sea, and Catocastro river valley.
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.
