Hillfort, Czacz
Narodowy Instytut Dziedzictwa pl

The hillfort is one of the border forts between Silesia and Greater Poland.

Location and description

The motte-and-bailey fort, known as Łysa Góra (Bald Mountain) or Żabia Góra (Frog Mountain) is located south of the village, among the meadows of the Samica river valley.

The shape of the hillfort approximates that of a quadrangle, with slight protrusions in the corner sections; it rises more than 4 metres above its base. A hollow measuring 20-23 m x 12-15 m is visible at the top of the embankment. In its centre stands a conical mound which J. Janosz referred to as a “keep”. Despite the large amount of peat present, the moat can still be identified, its width ranging from 2 to 3 metres. In the north, there are also remains of a causeway and a bridge.


A motte-and-bailey fort with an adjacent village existed here in the mid-14th century, continuing the traditions of a settlement complex consisting of a ring fort (Czacz 2a) and an ancillary settlement and cemetery, which were all abandoned in the late 10th/early 11th century. The fortified settlement on the Samica river was founded on the site of intensive prehistoric and early-historic settlement. The fortified settlement is overlaid with remnants of World War II-era trenches.

The site is believed to have been identified as early as during the first half of the 19th century, when the land around Czacz remained in the hands of count Marceli Żółtowski, the founder of an archaeological collection.

Condition and results of archaeological research
