Blatten Castle Ruins, Oberriet / Oberriet's Landmark Obert's landmark, once a proud castle fortress, has a rich history. It was built around 1230 by Abbot Berchtold von Falkenstein to defend his property. The castle has seen several landowners and was set on fire in 1799 during the battle for the Blatten ferry. The surviving remains consist of parts of the tower and the castle ramparts, as well as the vaulted cellar. The castle ruins are located in the southernmost part of the municipality of Oberriet on the Blattenberg, idyllically situated on the edge of the forest. On the fitness trail, which runs almost entirely through the forest, you can practice sports in complete harmony with nature. The castle restaurant is open from April to September. Members of the ski club host guests every Sunday and welcome visitors. The hut can be rented by the public from Monday to Saturday. Tours are welcome on Sundays.

Platten Castle, Oberriet Blatten Castle is a ruined castle in the municipality of Oberriet, in the canton of St. Gallen, Switzerland. The square keep stands not far from the Rhine on a rock south of the municipality of Oberriet. The family was first mentioned in 1170 with Burkardus de Blattûn and in 1229 with Ulricus de Blattenn. As chronicler Christian Kuchimeister reports, the castle was built shortly before 1270 by the Abbot of St. Gallen, Berchtold von Falkenstein, as protection against the Counts of Montfort-Werdenberg, in the territory of the Imperial Court of Kriessern, which, along with the Vogtherrschaft (reign of Thurgau and Zürichgau), had been granted to Heinrich Walter von Ramschwag (Lords of Ramschwag) in 1278 for his assistance to King Rudolf in the Battle of Marchfeld. It was then granted to Ulrich von Ramschwag in 1277. Due to his involvement in the Appenzell War, the castle and the lordship were temporarily confiscated as fiefs. In 1458, Walter Heinrich and Ulrich von Ramschwag sold the castle and estate to Jakob Mangold, a citizen of Constance. In 1486, it was repurchased by Abbot Ulrich Rösch of St. Gallen. From 1637 to 1640, Abbot Pius Reher commissioned renovations. The complex then served as the official residence of the Vögte von Kriessern until 1798. The castle was destroyed in the French War of Independence in 1799. Around 1911, part of the complex was used as a quarry. Plaque commemorating the restoration. The Canton of St. Gallen undertook the initial renovation of the tower. Further restorations were carried out on the tower in 1977 and on the surrounding walls and the remains of the castle gate in 1985. Aerial photograph (2016) The castle ruins are known to the people of the Rhine Valley as Blatten Castle. The grounds of the former castle complex and the interior of the tower (there are no longer any floors) are freely accessible. A later-built wooden building stands on top of the preserved vaulted cellar. This building is operated as a castle restaurant by the Oberriet Ski Club from April to September.
