Wyher Castle is a moated castle, which lies south of the village center of Ettiswil. It was first mentioned in 1304 as the home of the Freiherr von Wediswil. After passing through several owners, around the end of the 15th century it was acquired by the Feer family. Around 1510, Petermann Feer rebuilt it into a late-Gothic castle. In 1588 it was inherited by Ludwig Pfyffer von Altishofen, whose descendants adopted the name Pfyffer von Wyher. Between 1837 and 1964 it was owned by the Hüsler family, who were local farmers.
In 1964 a fire partially destroyed the castle and it was acquired by the canton. Renovations in 1981–83 and 1992–96 repaired the damage and restored the moat. In 1996 it became a museum, housing the Josef Zihlmann collection of local religious art.
References:La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a \'mound\' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group. Although they are termed \'passage graves\', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental.
