Cemetery with Polish gravestone monuments. Information about the cemetery has been published (see bibliography). According to Anna Lewkowska, Jacek Lewkowski and Wojciech Walczak, "in the south-western corner of the church square, there are two contemporary tombstones in the church cemetery. These are the graves of priests: the parish priest of Osowa Sykstus Hanusowski (died 1949), imprisoned in the gulags, and the prelate Antoni Bonkowski (died 1996)." The inscription from the first gravestone reads: "KS. PARISH PRIEST SYCSTUS / HANUSOWSKI / 1883-1949 / PEACE TO HIS SOUL".

According to Lewkowski and Walczak, the active Catholic cemetery has a rectangular plan and a 0.9 ha area surrounded on three sides by a stone and concrete fence. It was established around the middle of the 19th century and several tombstones have survived from that century. The two oldest were created in 1867. Their inscriptions read: "Here rests / in this grave / JULIA TUMICZEWICZOWA / DIED FROM THIS WORLD 1867 MAY (...)" and "D. O. M. / ETERNAL REST / PRAXEDA Z KALETKOWSKICH / JANUSZKIEWICZOWA / DECEASED 1867. DECEMBER / 29 D. AGED 66". To quote the aforementioned authors, "the northern side of the cemetery is completely new with tombstones from the 2nd half of the 20th century. (...) The state of preservation of the cemetery is good."
