Bosanska Dubica Mosque

Azizija Mosque (Azizija džamija) is a historic mosque in Kostajnica, originally built in 1862 by Ottoman Sultan Abdul-Aziz. The mosque was destroyed in 1992 and rebuilt in 2008.

The Jewish cemetery in Banova Jaruga was established in the 19th century and was later abandoned after World War II. The oldest found burial dates to 1915, and the latest to 1933. One of the most interesting monuments in the cemetery is the Rehnicer family ohel, built at the beginning of the 20th century in the Jewish Classicism architectural style.

The Jewish cemetery is located on a hillside in the southern part of the village. The Jews from Nova Gradiska also used the Jewish cemetery in Cernik. While the cemetery was founded in 1800, the oldest gravestone inscription dates to 1871. Some of the grave inscriptions are written in Hebrew, German, and Croatian. Among the more notable buildings in the cemetery include the Schmidek Schulzer family ohel, built as a mausoleum, and the ruins of a mortuary. The last burial took place in 1942.
