Hohensax is a ruined castle in the Sennwald. 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.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
