Construction of the church of St. Maximillian in Posavski Bregi was started at the beginning of the 19th century under the supervision of Zagreb bishop Maksimilijan Vrhovac, and was completed in 1815.

The interior of the church is vaulted, and the vault is decorated with carvings created at the time of construction.

The church has a particularly rich collection of church vestments, and the classicist church inventory is partially preserved.

The church is included in the Register of Cultural Properties of the Ministry of Culture of the Republic of Croatia.
