Like most of the castles in the Rhineland-Palatinate, Landeck Castle was built in approximately 1200. It served probably the function of protecting the nearby Klingenmünster monastery. The first documental reference to Landeck Castle was made in 1237.
In the period around 1500 there were castle administrators from the Kurpfalz, the bishop of Speyer and the counts of Zweibrücken. At the end of the 15th century extensive work was done at Landeck Castle. During the Peasants’ War in 1525 it was damaged, but obviously quickly repaired.
In 1570 there was again a change in ownership. After the dying out of the Zweibrücken-Bitch lineage their share of the castle went to the Kurpfalz. It was not until 1709 that the Electors succeded in owning the entire property of Landeck Castle, when the Speyer bishopric gave up the remaining quarter by exchange. The Kurpfalz remained the only owner until the French Revolution. In the 1960’s the castle was extensively restored.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.
