A very nice castle, good for taking photos if the cars weren't parked in front of it. Somehow that doesn't fit at all. The fact that the hotel operators don't do anything about it... a very bad image to the outside world...

Story. The castle was probably built at the beginning of the 12th century, in 1145 the Lords of Ratzenried were first mentioned. The reason for its construction was possibly the same as that of Praßberg Castle near Wangen in the Allgäu, which was begun in 1123. It was intended to secure the fiefs of the St. Gallen monastery in the region and collect the royalties from the courts. The lords of Ratzenried were also servants of the monastery. The Ratzenrieders died out at the end of the 13th century, but the new lords of the castle also called themselves von Ratzenried, they lost the castle again around 1350 and moved to the Ostallgäu. From 1353 the lords of Molpertshausen sat at the castle, in 1369 Hans von Molpertshausen was officially enfeoffed with the lordship by the St. Gallen abbot. About ten years later, the castle had to be sold again, among other owners it belonged to the Humpis of Ravensburg from 1453. They also called themselves Humpis von Ratzenried from the 16th century. Jos Humpis von Ratzenried had the castle restored in 1502 for 11,000 guilders, as it had collapsed down to the walls. They owned the castle until 1647. Razenried Castle was burned down by the Swedes during the Thirty Years' War in 1632 and was not rebuilt for cost reasons. In 1806 the castle passed to the Kingdom of Bavaria, which ceded the Ratzenried dominion to Württemberg in 1810. The complex came from him in 1813 to the Counts of Beroldingen, and in 1908 the Counts of Waldburg-Zeil inherited the castle. Source: Wikipedia

Count Franz Anton von Waldburg-Zeil inherited the county of Trauchburg in 1772. Since then the family has carried the name "Waldburg-Zeil-Trauchburg". Count Anton designated Mechensee as the new administrative center of the county. In 1785/86 the official building, today's Neutrauchburg Castle, marked the end of his extensive building work. It housed the chief office and the archives of the rulers. It was also Count Franz Anton who renamed Mechensee “Neutrauchburg”. Neutrauchburg Castle has only been used privately by the princely house of Waldburg-Zeil-Trauchburg since the 19th century, partly as a residence for the hereditary family and partly as a widow's residence for the princesses. From 1848 to 1856, the castle served as a private boarding school for Prince Constantin von Waldburg-Zeil-Trauchburg. The grandmother of today's Prince Erich von Waldburg-Zeil, Countess Monika, lived in Neutrauchburg Castle until her death in 1953. In 2008, the castle was extensively restored, converted into a hotel with great attention to detail and opened as a hotel and restaurant in the summer.

Depending on the direction, either the brakes or the muscles are used here. For me it was the brakes. :-)

Syrgenstein Castle is well worth a visit.👍🏻 Unfortunately, it can only be viewed from the outside, as it's privately owned. 🤷🏻♂️
