According to Anna Lewkowska, Jacek Lewkowski and Wojciech Walczak: "The active Catholic cemetery in Brzozówka is located outside the village. (...) It is fenced with a metal fence and covers an area of 1.9 ha. It was established on a rectangular plan, with an alley in the east-north and south-west direction dividing the cemetery into two parts." In the middle of the cemetery there is a slab made of granite with an inscription with the date of the establishment of the cemetery: "In memory of the consecration / of the cemetery / of the glassworks of the Niemen / On 21 November / 4 December 1905" The oldest gravestone, from 1905, belongs to Kazjmesz Pławski. Particularly noteworthy are the tombstones of Juliusz Stolle, owner of the Niemen glassworks, and his family. As the cited authors write: "These graves are situated by an alley, in the northern part of the cemetery establishment. Made of black granite, the gravestone of Juliusz Edward Stolle is surrounded by a square grave field (...). In the centre of the field is a rectangular, horizontal tombstone. Behind the slab, on a pedestal base, is a stele with sides slightly tapering upwards. On the front of the stele is a deep-carved cross and below the cross is a bronze oval portrait medallion with the likeness of the deceased Julius Stolle. On the right side of the medallion the signature: 'fecit B. Mazurek, 1929", indicating that the medallion was made in a well-known Warsaw workshop (...). In front of the stele, on a plinth base, a rectangular vertical gravestone of Edward Stolle, a lieutenant of the Polish Army, killed near Radzymin in 1920. Next to the grave of Edward and Juliusz is the gravestone of the Stolle family's children (...). "Noteworthy is the inscription from the gravestone of Jan Budyński: "JAN BUDYNSKI / MANAGER OF THE NIEMAN SCHOOL / SODALIS MARIANUS / SCOUT OF THE REPUBLIC OF POLAND / DIED. 10 JANUARY 1927. / LIVED 23". In the cemetery, in its northern part, the graves of Home Army soldiers executed in 1944, including Czesław Gawryłkiewicz and Franciszek Glejzer, are located.

Most of the tombstones in the cemetery are contemporary, and the cemetery itself is maintained in very good condition, "a testimony to the positive, social action of the former owners of the 'Niemen' glassworks".
