Built in 1192, the Torpo stave church is the oldest building within the valley and traditional district of Hallingdal. The church was dedicated to Saint Margareta. The stave church was purchased by the municipality in 1875. It was initially planned to expand it with an annex to the east, but in 1879 it was decided instead to modernize the interior with new ceiling and gallery. Following protest from the Ancient Monuments Society, the municipality decided to build a new church on the adjacent property. The new church was built north of the old one with the two churches standing side by side.
The Torpo stave church is one of two stave churches that are signed by the their craftsmen, the other being the church at Ål. In both churches a runic inscription reads: Torolf built this church. The full runic inscription in the Torpo stave church, which is listed as N 110 in the Rundata catalog, reads: Þórolfr made this church. Ásgrímr, Hákon, Erlingr, Páll, Eindriði, Sjaundi, Þórulfr. Þórir carved. Ólafr.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
