Frischenberg is a ruined castle in Sennwald, canton of St. Gallen, Switzerland. It was built in the early 14th century by the lords of Hohensax, probably by Ulrich III von Hohensax some time after 1313. It was destroyed and rebuilt in 1446, and abandoned in 1551.
Sennwald is a municipality in the Wahlkreis (constituency) of Werdenberg in the canton of St. Gallen in Switzerland.
The canton of St. Gallen, also canton of St Gall, is a canton of Switzerland. The capital is St. Gallen.

Hohensax is a ruined castle in the Sennwald municipality in the Swiss canton St. Gallen. The castle was built around 1200 by the barons of Sax, and was destroyed in 1446. In 1248, the castle passed to Ulrich von Sax, founder of the Sax-Hohensax line of the noble family. The castle was plundered in a feud of 1393, and sold together with the villages of Sax and Gams to the dukes of Austria. In the Old Zürich War, the people of Appenzell captured and slighted the castle in 1446. After this, the barons of Hohensax resided in the nearby Forstegg castle at Salez. In 1640, the ruin passed to the barony of Sax-Forstegg, one of the constituent parts of the canton of Linth of the Helvetic Republic in 1798, and later the canton of St. Gallen. It included the villages of Sax, Salez and Gams.
The castle was sold to duke Leopold IV of Austria in 1393 along with the Hohensax lordship, but returned to Ulrich Eberhard IV of Hohensax as a fief. In the Appenzell War of 1405, the castle was occupied by Appenzell and became detached from the lordship of Hohensax. It was bought by Ulrich von Hohensax in 1440, but in 1446, the castle was again attacked by Appenzell, in the context of the Old Zürich War, and was destroyed. Frischenberg was bought to Albrecht V of Hohensax in 1454. After the St. Gallerkrieg of 1489/90 it passed to the Swiss Confederacy, who gave it to Ulrich IX of Hohensax. Ulrich incorporated the lordship of Frischenberg into Sax-Forstegg in 1517. The castle was abandoned by Ulrich Philipp von Hohensax, who built his new residence in Sax (now part of Sennwald municipality).
Leopold IV of Austria, Duke of Further Austria, was an Austrian Habsburg Duke of the Leopoldinian Line, known as "the Fat".
Appenzell is a historic canton in the northeast of Switzerland, and entirely surrounded by the canton of St. Gallen.
The Old Zurich War, 1440–46, was a conflict between the canton of Zurich and the other seven cantons of the Old Swiss Confederacy over the succession to the Count of Toggenburg.
