Grünenberg castle ruin, Medieval castle ruin in Melchnau, Switzerland
The stone remains of Grünenberg Castle stand on a hill, forming part of a complex with Schnabelburg Castle and Langenstein Castle ruins.
The Barons of Grünenberg constructed this fortification between the 11th and 12th centuries, ruling the Oberaargau region until the 15th century.
The site reflects medieval architectural techniques and represents a class B Swiss cultural property, preserving regional historical heritage.
Visitors reach the castle ruins through a marked hiking trail from the Melchnau Oberdorf parking lot, requiring a 10-minute walk uphill.
The castle complex demonstrates medieval power structures through its three interconnected fortifications, built as the ruling family branches expanded.
