Bílá Voda (German: Weißwasser/Märkirsch Weißwasser, Polish: Biała Woda, all meaning "white water") is a village and municipality (obec) in Jeseník District in the Olomouc Region of the Czech Republic. The municipality covers an area of 14.98 square kilometres (5.78 sq mi), and has a population of 282 (as at 2 October 2006).
Bílá Voda lies on the northern slope of the Golden Mountains range of the Eastern Sudetes, at the westernmost point of the Czech Silesia region, close to the Polish border at Złoty Stok. It is located approximately 31 kilometres (19 mi) north-west of Jeseník, 98 km (61 mi) north of Olomouc, and 182 km (113 mi) east of Prague. In the east it borders the municipal area of Javorník. The village is named after the Bílá Voda mountain stream, a tributary of the Nysa Kłodzka river and part of the Oder basin. About two thirds of the municipal area are covered with forests.
The settlement in the Silesian Duchy of Nysa was probably founded with Bílá Voda Castle in the 13th century. From 1507 onwards the Prince-Bishops of Wrocław had the castle rebuilt as a summer palace. Weißwasser was first mentioned in a 1532 deed. Jakob Ernst von Liechtenstein-Kastelkorn, the later Bishop of Olomouc, established a Piarist college on his inherited Bílá Voda estates in 1723, a response to the 1707 Convention of Altranstädt granting religious freedom to the Silesian Protestants. When the Prussian king Frederick the Great conquered most of Silesia in 1742, the Duchy of Nysa was divided and Bílá Voda became a border town of Austrian Silesia, after World War I part of the newly established state of Czechoslovakia. In 1930, Bílá Voda had a population of 1104, of which 941 were German-speaking. Upon the 1938 Munich Agreement the area was annexed by Nazi Germany and incorporated into the Reichsgau Sudetenland. After 1945 the German population was expelled according to the Beneš decrees.
