The first church in Czernice was built from the foundation of Jakub Poczta from Czernice, later a castellan of Ciechanów, after 1398, when a parish was established in the village. Church dedicated to Saint Achatius and the Companions was created at the beginning of the 16th century. It was seriously damaged in 1915 during the Przasnysz Battle, but it was rebuilt in 1933 and renewed several times in later years. As a result of these works, the sacristy and western façade were transformed.
The church was built in the middle of the village on an artificial hill. It is a brick, late-gothic, one-nave building with a chncel narrower than the nave, ended from the east by a straight wall. The sacristy adjoins the presbytery from the north, and a slightly later porch from the south. Both stepped gables of the church are decorated with blendes, pilasters that pass into pinnacles and wimpergs with circular openings. Church is a characteristic example of the Mazovian late gothic.
