The rampart in Kuznica Skakawska village (near Wieruszow) is an enormous fortified settlement covering the area of 48 ha and with 600-700 m in diameter.

An enormous fortified settlement covering the area of 48 ha and with 600-700 m in diameter is limited by the rivers Prosna and Niesob and from the south by the embankment 440 m long and 4 m high. The place has been considered to be the remnant of the fortified settlement of the culture of Luzyce region (700-400 years B.C.). In 1964 four ornamented vessels dating back to so called “Roman influences” (c the 1st AD) were excavated in the area. Ptolemy, an ancient geographer, marked this place as “Arsonium” on his map. Excavations can be seen in the Archaeological Museum in Lodz. It is not far from the settlement to the ruins of the castle in Wieruszów and the monastery of Pauline monks. Both these places are linked by a tourist trail “From Ptolemy to Wierusz”.
