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 Przewodziszowice watchtower is the ruin of a medieval stronghold hidden in the forest on the outskirts of Żarki, in the heart of the Kraków-Częstochowa Upland. A fragment of a defensive wall up to 10 meters high has been preserved, which is the remains of a tower built probably in the 14th century. The watchtower could have served as an auxiliary function for the nearby Ostrężnik Castle, and according to legends, it was the seat of the robber knight Mikołaj Kornicz, who attacked the nobles and hid treasures in rock crevices. A forest path leads to the ruins - the terrain is rocky and uneven, so it is best to ride a mountain bike. This is an atmospheric and lesser-known place on the Trail of the Eagles' Nests. Right next to it is a rest area with a shelter and trail markings.

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.

The Church of St. Giles in Zrębice is a wooden, historic temple from 1789, built on the site of an older building on the initiative of parish priest Wojciech Buliński. It is located on the Wooden Architecture Trail of the Silesian province and attracts attention with its baroque interior, including altars, a 17th-century figure of Jesus and a cult painting of St. Giles. The church has a log structure, covered with shingles, and in the surroundings it is also worth seeing the historic bell tower and monumental linden trees.
