Mierzyn is a village in Poland, located in the Łódź Voivodeship, within Piotrków County, in the administrative district of Gmina Rozprza. Its history dates back to at least the 14th century, when a pagan temple existed there, later replaced by a wooden church mentioned in the Chronicles of Jan Długosz. The parish in Mierzyn has been established since 1399, and excavations carried out in 1881 uncovered coins from the 14th century, confirming the ancient origins of the settlement. In the 15th century, the village belonged to the Mierski family, and by the turn of the 19th century, it was owned by Karol Stefan Burghard, a philanthropist and renowned agriculturist.
The Church of St. Nicholas, a late Gothic structure from the 14th century, has been preserved, featuring an annex and a tower added in the 1830s. The church houses valuable historical artifacts, including a baptismal font from 1609 and paintings from the 17th and 18th centuries. Additionally, an 18th-century chapel with a statue of the Sorrowful Christ stands beside the church.
During the January Uprising, Mierzyn played a significant role, with Father Ignacy Bogusławski supporting the insurgents and imbuing local events with a patriotic spirit. After the uprising was suppressed, the village faced repression but continued to grow considerably. Following Father Bogusławski’s death in 1882, he was succeeded by Father Leon Offmański, who also left his mark, and later by Father Antoni Józef Christoph, who contributed significantly to the renovation of the church.
With its rich history and architecture, Mierzyn exemplifies a locality where local culture intertwines with major historical events.
