Książ is a castle in Wałbrzych in Lower Silesian Voivodeship, Poland. It was built in 1288-1292 under Bolko I the Strict. It lies within a protected area called Książ Landscape Park, overlooks the Pełcznica River and is one of the city’s main tourist attractions. (Wikipedia)
The day we went to visit that place was so foggy, that we hardly could see anything 😛
Just another 2000m further there is Botanical Garden in Wałbrzych – where you can admire many exotic plants and flowers.
