Schloss Wickrath was built between 1746 and 1772 by count Wilhelm Otto Friedrich von Quadt. The Baroque palace was built to the foundations of late medieval water castle. The original castle was demolished in 1859 by the Prussian administration. The current ensemble of buildings in the park, the Baroque west and east wing and the so-called Landstallmeisterhaus, the residence of the former stud master were built in 1875. The park has the shape of a coronet of a count of the Holy Roman Empire.
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.
