Oberdiessbach Castle German: Schloss Oberdiessbach (also called Neues Schloss) is a castle in the municipality of Oberdiessbach of the Canton of Bern in Switzerland. It is a Swiss heritage site of national significance.
The town of Oberdiessbach (known as Diessbach until 1870) was the center of the late medieval Herrschaft of Diessbach. The first castle in the area, Diessenberg on the Falkenfluh was built above the town and was destroyed in 1331. In 1546 Niklaus von Diesbach built the Alte Schloss (Old Castle) on the valley floor near the town. In 1666, near the Old Castle, construction began on the Neue Schloss or New Castle for Albrecht von Wattenwyl (1617-1671). Albrecht von Wattenwyl had been a commander of the Swiss Guard in service to the French king. So, he had the castle built in the french late Renaissance style. It was built by the Neuchatel architect Jonas Favre. The castle exterior remained generally unchanged after initial construction finished in 1668. The only major changes occurred around 1720, when the gate house was converted into a prison and in the 1850s when the garden was redone in the English style. The garden remained an English garden until 2005 when it was converted back into a Baroque style garden.
