As mentioned , the Waschhüsle was established by the ruler family of Liechtenstein in 1862 as a washhouse with a torkel extension for the production of wine . The western part of the building is a two-storey extension with an own ridge , built in 1897 . The interior of the building was changed many times , but today we cannot see any traces of its first facilities and rooms , as it was changed in a 20th century project .
