Włocławek - Kościół św. Jana Chrzciciela

In the 11th century a settlement existed on the Vistula River, which since 1123 has been the seat of a bishopric subordinate to the Archbishop of Gniezno, and in 1261 received town rights. At that time the town's name was Leslau. In the 14th and 15th centuries, the town was destroyed and subjugated several times by Teutonic Knights. Only the Peace Treaty of Thorn in 1466 finally secured peace.

After that, the grain trade flourished until the Swedish invasion in 1657 partially destroyed the town.

After the Second Partition of Poland, Włocławek fell to Prussia in 1793, and after the Congress of Vienna in 1815, the town became part of the newly formed Congress Poland, which belonged to Russia.

The construction of the late Gothic church began at the turn of the 14th and 15th centuries on a hill above the Vistula River, where a church already stood from the 12th century. In 1538 it was consecrated. In 1580 a tower was added to the west, and in 1622 the presbytery was enlarged with a semicircular apse.

In the past, the parish church, dedicated to St. John the Baptist, was flooded several times. Only the construction of dams in the 19th century prevented the church from being flooded.
