We recommend starting the walk around the city from the ruins of the old fashioned castle. Apparently, a long time ago, in the place where the castle tower stands today, there was an inn, to which a prince traveling around Greater Poland came. It was here that he was warned of robbers prowling in the area. To commemorate this event, the prince ordered to build a castle, church and castle, and call it OSTRZEŻÓW (according to historical sources, the name of the city comes from the name Ostrzesz). The beginning of construction of the castle as a fortification element is assumed in the first half of the fourteenth century, when Kazimierz Wielki began a powerful undertaking to strengthen the protection of Poland's borders. Built on an artificial hill, the defensive castle was the seat of the Ostrzeszów staroste. It was demolished during the Swedish invasion, although it was partially rebuilt and was the court seat until the end of the 18th century, it never returned to its former glory.
