Rheinfels Castle construction was started in 1245 by Count Diether V of Katzenelnbogen. After expansions, it was the largest fortress in the Middle Rhein Valley between Koblenz and Mainz. It was slighted by French Revolutionary Army troops in 1797.
The main entrance to the castle complex is a tall square clock or gate tower (~1300 AD) opposite the hotel. A connecting path joins the clock tower to the remains of the living quarters of the Earls of Hessen-Darmstadt (the so-called Darmstadt Building). The Darmstadt building was designed in Tudor style with pointed gables. The connecting path was the site of the former moat of the main castle buildings; part of which is now the large cellar or basement. This large cellar was arched over in 1587-89 in two visible phases. It is the largest self-supporting vaulted cellar in Europe and has a length of 24 metres, a width and height of approximately 16 metres and can accommodate up to 400 people.
The walls are up to 4 metres thick. Previously a 200,000 litres wine barrel was constructed for storage. The cellar was renovated in 1997 and restored to its original condition and now serves as a meeting place for concerts, theater performances, and other shows.
The castle museum is located in the former castle chapel which is the only finished room of the original castle. It is accessed through an internal gate and up the path. The museum contains a model reconstruction of the castle before its destruction giving one a sense of how big the castle used to be. The medieval castle courtyard is found beyond the castle museum building (slightly uphill). This was the center of the medieval castle which contained a bakery, pharmacy, garden, brewery, well, and livestock—which would have allowed it to withstand an extended siege. Remnants of the original 13th-century plaster which was painted white can still be found on some walls.
While much of the castle is a ruin, some of the outer buildings are now a hotel and restaurant.
References:The Beckov castle stands on a steep 50 m tall rock in the village Beckov. The dominance of the rock and impression of invincibility it gaves, challenged our ancestors to make use of these assets. The result is a remarkable harmony between the natural setting and architecture.
The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
