Tenczyn Castle (Poland)
The Tenczyn Castle, otherwise known as the Tęczyn Castle, is a medieval castle in the Polish Jura, in the village of Rudno, Poland. It was built as a seat of the powerful Tęczyński family. The castle fell into ruin during the Deluge in mid-17th century, after being pillaged and burned by Swedish-Brandenburgian forces looking for the Polish Crown Jewels and rumored treasures of the Tęczyński family. Subsequently rebuilt, after a fire in the mid-18th century it again fell into disrepair and remains in that state to this day.
Castle stands on rocks which are remnants of Permian lava stream, constituting the highest hill of Garb Tenczyński.
