Ortenburg castle was erected in the late 11th century by ministeriales of the Bavarian Prince-Bishops of Freising, who then held large possessions in the Duchy of Carinthia. Their descendants began to call themselves Counts of Ortenburg. The castle is located on the northern slope of the Gailtal Alps overlooking the Drava valley.
Damaged by the 1348 Friuli earthquake, the significance of the castle diminuished after the extinction of the Ortenburgs in 1418. The estates were inherited by Count Hermann II of Celje and in 1456 finally seized by the Imperial House of Habsburg. In 1524 the comital title passed to Gabriel von Salamanca, who had his new residence, Porcia castle built in the nearby town of Spittal an der Drau.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.
