Schloss Grynau and country inn

The tower is still preserved (from the 13th century), formerly owned by Zurich, Toggenburg and Habsburg, then transferred to the property of the Canton of Schwyz. Next to it the country inn (closed Tues / Wed), moderate feedback on the internet (!?)

History of the castle complex (castle tower)
In the years 965/72 the German emperors donated the two farms Pfäffikon and Wollerau to the Einsiedeln monastery. The Benedictine monastery built a storage facility in Pfäffikon to store the population's donations in kind.
In the middle of the 13th century, Abbot Anselm von Schwanden had today's castle tower built to ward off enemy attacks and to protect the income from the monastery lands. Since the complex repeatedly had to serve as an abbot's residence, residential buildings were built near the tower complex under the direction of Abbot Burkhard von Weissenburg at the beginning of the 15th century. From then on the castle was called the «Weissenburg».
The complex was very important for Einsiedeln Abbey, as the following examples illustrate. In 1480 the abbot was elected here, and in 1577 it served as a place of refuge for the Einsiedeln monks for 7 months when the monastery and the village of Einsiedeln fell victim to a major fire. The "Weissenburg" also repeatedly received important visitors such as various Schwyz bailiffs and magistrates and the papal nuncio. The castle complex served the monastery as an administrative center until the 18th century and was finally replaced by the newly built baroque governor's office next to it.
As a defensive structure, Pfäffikon Castle was not only subordinate to Einsiedeln Abbey, but also to the governors of the courts, the Lords of Rapperswil, the Counts of Habsburg, Zurich and Schwyz. As a result, the castle was involved in numerous military conflicts.

Gesslerburg Ruins

The "nobles of Küssnach" and the lords of Silenen as lords of the castle
Gesslerburg is the name of the medieval castle in Küssnacht. Like Hohle Gasse in Immensee, it is linked to the legend of Wilhelm Tell. According to the historian Aegidius Tschudi, it is said to have been the seat of Landsvogt Hermann Gessler. The ruins of the Gesslerburg have been owned by the Swiss Confederation since 1908.
The ruins of the hilltop castle are located on a hilltop in the east of the village, above the village stream, which flows from the Seebodenalp into the lake. A path leads up to the Gesslerburg from the Knochenstampfe, a shed by the stream with a water wheel in which fertilizer was once produced.
Despite archaeological investigations, very little is known about the origin and history of the castle complex. There is evidence of a nobleman named Recho from the second half of the 9th century, who donated his possessions in Küssnacht to the Benedictine monastery in Hof Luzern, along with other goods. An early medieval castle probably also belonged to it. The first documented mention dates back to 1263: «in castro nostro Chüssenach».
In 1291, Küssnacht was bought from the monastery by Rudolf I of Habsburg. The lords of the castle, who were employed as bailiffs by the House of Habsburg, appeared as "nobles from Küssnach". Knight Eppo II (1282-1315) demanded taxes, duties and forced labor as a bailiff. In 1302 there was a dispute with the villagers of Küssnacht, Immensee and Haltikon, in which the bailiff is said to have almost died. Around the middle of the 14th century. The castle was destroyed by fire and then rebuilt much larger.

Anyone who has made it to the castle, which today only consists of a tower, should add another hour: a simple hike through the Bätzimatt der Linth nature reserve or along the Linth Canal is a real stunner! Further information: https://www.teddy-b.ch/excursions/baetzimatt-tuggen-sz-linth-ahoi/
