The wooden church of the Assumption of the Blessed Virgin Mary was built in Miasteczko Śląskie in the years 1666-1667. For many decades, it was a branch church of the parish in Żyglin. The building was erected in a log wall construction, with a shingle roof. A slender bell tower and arcades used as shelter for pilgrims, who encircle the church, are worth attention. There is a gate to the church premises located in a freestanding bell tower.
