Trachselwald Castle is located in Switzerland in the Canton of Bern and was was originally built in the mid 12th Century as a fortress. Additions were made over the centuries when the castle was used first as a manor house, and later as a prison.
The castle consists of a square keep with a small courtyard surrounded by buildings. The original gatehouse was demolished in the 18th Century and a new gatehouse incorporating ramps was built.
My reconstruction of Trachselwald Castle is 40 x 30 inches (128 x 96 studs) and is about 22 inches high.
