Genhoes Castle was first mentioned in 1041. Then it was probably just a fortified tower house. In 1381 it was owned by a Johan van Alden-Valkenborch. Before 1444 it came into the hands of Jan 't Zievel. He left it to his son-in-law Hendrik van Ghoor. He, or his son Willem, probably built the present square tower and the west wing. The walls of the tower are around 1.6 meters thick. He also built a gate tower, which has disappeared, at the site of the present gate arch to the bailey. It may be possible that the castle had been destroyed shortly before, during the Burgundian wars under Emperor Maximillian of Austria. Then followed almost 150 years of family disputes and lawsuits which resulted in the assignment of the castle to the King of Spain as Lord of the Southern Netherlands in 1661.
In 1701 the castle was bought by Georg, Baron of Tunderfeld. He was born in Latvia and had served as a general-major in the service of Emperor Leopold I of Austria. In 1749 the castle was again sold, but now to Leonard Thimus, a cloth manufacturer from Aachen. He built the front wing and the arched bridge on medieval foundations thus creating the L-shaped castle we see today. Beneath the entrance was a prison that fell out of use in 1670. His son-in-law Johann Friedrich von Pelser, Lord of Berensberg built the present U-shaped bailey.
In 1814 Oud-Valkenburg was definitely added to the Kingdom of the Netherlands. In 1944 the castle was continuously occupied by retreating German soldiers. The castle is now owned by Natuurmonumenten; an association for nature conservation and environmental protection. They rent the castle out and it is now used as a farm. The castle is private property and thus can not be visited.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.
