The Catholic cemetery in Czarny Ostrów is located on the left side of the road to the village of Antonówka, next to the municipal cemetery. It is an old cemetery. Several tombstones date to the end of the first half of the 19th century, the oldest one found by Zbigniew Hauser has an inscription indicating the year of death 1839 ("Podolski" cross). Hauser lists 25 tombstones with inscriptions, as well as numerous unnamed and broken ones, including two that stand out for their size and ornamentation: one with an acroterion and the Eye of Providence, the other - a magnificent tombstone - decorated with an arcaded frieze. Among the outstanding ones Hauser counts the impressive black marble tombstone of the Zaleski family decorated with the Prawdzic coat of arms (from the end of the 19th century), that of Domicela Krentowska (d. 1869), an equally impressive stone tombstone topped with a cross with a bas-relief of a saint and neo-Gothic decoration, and that of a doctor, Kazimierz Nitkowski, with traces of a photograph or coat of arms. The cemetery also has cast-iron tombstones, as well as those in the shape of a knotted trunk and a knotted cross.

Zbigniew Hauser also mentions the parish church, whose vaults contained the tombs of the Przeździecki family, owners of the estate. Even in Soviet times they were completely looted and destroyed. Only a short fragment of one of the epitaphs has survived.

On the website Genealogia Polaków one can find photographic material partly overlapping with the tombstones mentioned by Hauser, but also showing photographs of other tombstones not noted by the author of the publication https://genealogia.okiem.pl/album/668 .

In the last ten years the cemetery has been cleaned up several times by the inhabitants of the town https://misje-jezuickie.pl/cmentarz-czarnym-ostrowie/ .
