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:The Roman Theatre of Mérida is a construction promoted by the consul Vipsanius Agrippa in the Roman city of Emerita Augusta, capital of Lusitania (current Mérida). It was constructed in the years 16 to 15 BCE. One of the most famous and visited landmarks in Spain, the Roman Theatre of Mérida is regarded as a Spanish cultural icon and was chosen as one of the 12 Treasures of Spain.
The theatre has undergone several renovations, notably at the end of the 1st century or early 2nd century CE (possibly during the reign of Emperor Trajan), when the current facade of the scaenae frons was erected, and another in the time of Constantine I (between 330 and 340), which introduced new decorative-architectural elements and a walkway around the monument. Following the theatre"s abandonment in Late Antiquity, it was slowly covered with earth, with only the upper tiers of seats (summa cavea) remaining visible.
