Burg Ostrężnik (Polish Zamek Ostrężnik) is a castle ruin near Janów, not far from Częstochowa in the Kraków-Częstochowa Jura. The castle belongs to the Eagle's Nests castles, which secured the border between the Kingdom of Poland and the Holy Roman Empire in the 14th century. It is located in the Silesian Voivodeship, but historically belongs to Lesser Poland. (Wikipedia)

The royal castle, probably built by Casimir the Great, was an important defensive point in the Middle Ages. In the 16th century, the castle was attacked many times, including by the troops of Archduke Maximilian. The ruins of the castle in Olsztyn near Częstochowa are picturesque remains of a 14th-century stronghold on the Eagle's Nests Trail. It is located on a hill, and its distinctive feature is a 35-meter high cylindrical tower.

Ostrężnik Castle is a mysterious ruin hidden in the forest near the village of Siedlec, on a limestone hill 380 m above sea level. Although little is known about its history, it is believed that it was built in the early 14th century and may never have been completed. Fragments of walls, ramparts and the outline of the former castle grounds have survived to this day. Right next to it is the Ostrężnicka Cave, which is often visited by speleologists. The place is shrouded in legends of robber knights and insurgent treasures. A forest path leads to the ruins - an MTB or trekking bike with good grip will be the best.
