Wenecja Castle Ruins (Venetian Devil's Castle)

The Wenecja Castle ruins (say "veh-NETS-yah"), known locally as the castle of the Venetian Devil, are the remains of a 14th-century Gothic stronghold on a strip of land between two lakes in Poland's Pałuki region. A grim legend about a merciless judge, walls of brick and fieldstone, and a narrow gauge railway museum next door make this a rewarding stop on a day trip to the famous Biskupin archaeological site.

Where it is

Wenecja is a village a few miles south of Żnin ("zhneen"), in the Kuyavian-Pomeranian region of north-central Poland. The nearest big cities are Poznań (about 86 km to neighboring Biskupin, roughly 1 hour 10 minutes by car) and Bydgoszcz (about 44 km to Żnin, around 40 minutes). From Warsaw, the drive takes about three and a half hours. There is no mainline rail service to Żnin, so come by car.

A short history

The exact date of construction is uncertain. The Pałuki Regional Museum, which looks after the site, gives around 1390, while other sources place it in the mid-14th century. The castle is linked with Mikołaj Nałęcz, a judge from Kalisz and lord of Wenecja, who, according to tradition, named the village after Venice. It guarded the road from Żnin to Gniezno, Poland's first capital.

The fortress was partly damaged as early as 1395 during a feud between two noble clans. From 1420 it belonged to the archbishops of Gniezno, who expanded it with an outer wall and round towers designed for gunpowder weapons, counted among the earliest fortifications of this kind in Poland. Tradition says it also served as a prison for clergy and opponents of the Church. Once the threat from the Teutonic Knights faded, the castle lost its purpose and was dismantled (the end of the 15th or the 16th century, depending on the source); its bricks went into the archbishops' new residence in Żnin.

The legend of the Venetian Devil

Nałęcz was said to hand down such ruthless sentences that people called him the Bloody Devil. Local lore claims his ghost still haunts the walls. Another story says cannons were test-fired here before the Battle of Grunwald in 1410, one of the largest battles of medieval Europe; the museum treats this as legend, not established fact.

What to see

The castle was laid out as a square with 33-meter sides. Today you can walk around substantial sections of the outer walls and the inner courtyard. Look for the northeast corner, where a defensive tower (also used as a prison) once stood, and the south side, where a drawbridge crossed the moat. Knightly tournaments and festivals are held on the meadow in front of the ruins.

Is it worth visiting?

On its own, the ruin is a 30 to 45 minute visit. Combined with the railway museum (same ticket) and Biskupin, it is well worth it, especially for families. The ground is grassy and uneven, so sturdy shoes help. Information on site is mostly in Polish.
