Sisak Cathedral was built in the 18th century and dedicated in 1765. The spire was built in 1760.
After an earthquake in 1909, the old Baroque facade was replaced with a Neoclassical facade, with details in the Art Nouveau style. The church was also damaged during the Croatian War of Independence.
On 5 December 2009 Pope Benedict XVI established the Diocese of Sisak. As a result, the parish church became a cathedral.
