Psychiatric Hospital of Marianne of the Netherlands in Bílá Voda, Psychiatric facility in Bílá Voda, Czech Republic.

The Psychiatric Hospital of Marianne of the Netherlands in Bílá Voda occupies a Baroque château first mentioned in 1691 as a stone noble residence, 36.6 m long and 13 m wide. Princess Marianne of Orange-Nassau had it rebuilt in 1854 and raised by one storey. It stands about 370 m above sea level on a slope of the Góry Złote, surrounded by an old walled park.

Franz Karl von Liechtenstein-Kastelkorn had a Baroque château built at Weißwasser shortly after inheriting Hertwigswaldau in 1684; it was first recorded in 1691 as a Rittersitz. Princess Marianne of Orange-Nassau bought it in 1853 and had it rebuilt and raised by one storey in 1854. After 1945 it was expropriated and nationalised, and in the 1980s it became the seat of the district public health office.

The palace is named after Princess Marianne of Orange-Nassau, who bought the estate in 1854 and had it rebuilt and raised by one storey. The psychiatric clinic that occupies it today also carries her name, Psychiatrická nemocnice Marianny Oranžské. In the park stand two sandstone sculptures from the 1760s, Saint Florian and Saint Wendelin, and a column commemorating Emperor Joseph II.

The château stands about 2 km from the centre of Bílá Voda, at the end of the road from Javorník, with a bus stop directly in front of the building. The palace itself is a working psychiatric hospital and cannot be visited; the walled park around it, with its two sandstone sculptures and the Joseph II column, can be walked through.

Princess Marianne bought the estate in 1854 and had the château rebuilt and raised by one storey. The psychiatric clinic that now occupies it is named after her, although she never saw it as a hospital.
