The castle in Venice was one of the first private defense castles in Poland. In the 1960s, after archaeological research, the building was secured in the form of a permanent ruin. The castle courtyard is available for tourists for a fee. The purchase of the ticket also entitles you to visit the Narrow Gauge Railway Museum located in the vicinity. It is also possible to visit both sites with a guide.
Built in the 14th century, the castle used to guard the trade route connecting Żnin with Gniezno. It owes its original name to its most famous owner - Mikołaj Nałęcz. According to old legends, Judge Nałęcz was an extremely harsh man and he issued sentences like that, which made him known as the Bloody Venetian Devil. It is said that his spirit haunts the ruins to this day.
As the castle was located in the areas controlled by the Teutonic Order, it is said that here bombards were tested before the Battle of Grunwald. Already in the 16th century, the stronghold was partially demolished, and the brick was used to build the archbishop's palace.
