Wałbrzych (; ; ; or Walmbrich; or ) is a city located in the Lower Silesian Voivodeship, in southwestern Poland. From 1975–1998 it was the capital of Wałbrzych Voivodeship; it is now the seat of Wałbrzych County. Wałbrzych lies approximately southwest of the voivodeship capital Wrocław and about from the Czech border. Wałbrzych has the status of municipality. Its administrative borders encompass an area of with 110,000 inhabitants, making it the second-largest city in the voivodeship and the 33rd largest in the country. Wałbrzych was once a major coal mining and industrial center alongside most of Silesia. The city was left undamaged after World War II and possesses rich historical architecture; among the most recognizable landmarks is the Książ Castle, the largest castle of Lower Silesia and the third-largest in Poland. In 2015 Wałbrzych became widely known due to the search for an allegedly buried Nazi gold train, which however was not found. Etymology According to the city's official website, the early Polish name of the settlement was ('forest castle'). The German name (also meaning 'forest castle') referred to the castle Nowy Dwór (German: ), whose ruins stand south of the city; the name came to be used for the entire settlement. It first appeared in the 15th century. The modern Polish name Wałbrzych comes from the German name , a late medieval variation of the older names or . History Middle Ages Polish sources indicate the city's predecessor, Lasogród, was an early medieval Slavic settlement whose inhabitants engaged in hunting, honey gathering, and later agriculture. Lasogród eventually developed into a defensive fort, the remains of which were destroyed in the 19th century during expansion of the city. However, some German sources say no archaeological or written records support notions of an early West Slavic or Lechitic settlement nor the existence of a castle before the late 13th century. They also denounce the idea that during the Middle Ages the area of Wałbrzych was part of an unpopulated Silesian forest, known as the Silesian Przesieka. In April 2022, a coin hoard was discovered near Wałbrzych dating from the first half of the 13th century. According to 17th-century Polish historian Ephraim Naso, Wałbrzych was a small village by 1191. This assertion was rejected by 19th-century German sources and by German historian Hugo Weczerka, who says the city was founded between 1290 and 1293, and was mentioned as Waldenberc in 1305. He
