Church of the Assumption of the Virgin Mary, Chełmno

The Church of St. James the Elder and St. Nicholas was built in the 13th and 14th centuries as a Franciscan church. The year 1806 marked the dissolution of the Franciscan order and the conversion of the church into a civil building such as a grammar school in 1859.

The Chełmno convent is a 13th century Cistercian monastery, now run by Benedictine nuns. The monastery complex includes the Gothic monastery with the medieval treasury and cellar, the 13th century Mestwin tower, the hospital building, the convent garden and the Gothic church of St. John the Baptist and St. John the Evangelist (1290-1330) with the crypt of Abbess Madeleine Mortęska .

The Collegiate Basilica of St. Nicholas was founded in the 13th century. From the mid-16th century until its end and again during the Swedish flood (1656-1659), the church was evangelical. In 1896 a complete renovation of the façade in the neo-gothic spirit took place, the interior was given new polychrome and stained glass windows. During the war, in 1945, the church suffered heavy losses. The reconstruction took place in the years 1946-1949.
