Župna crkva sv. Petra i Pavla u Osijeku

On the site of the present church, there was a cemetery and a small chapel, and in 1732 a Baroque parish church was built. As Osijek grew in the 19th century, the church became too small and inadequate, which prompted Bishop Josip Juraj Strossmayer to take the initiative to build a new one in 1866. The competition for the design was won by the German architect Franz Langenberg in 1892, but after his death in 1895, construction was taken over by Richard Jordan. The foundation stone was blessed in 1894, and the church was consecrated in 1900.

The church, built of 3.5 million bricks, has a 94-meter-high tower and a capacity for over 3,000 worshipers. The interior is decorated with neo-Gothic ornamentation and frescoes by Mirko Rački (1938–1942). During the Homeland War in 1991, the church suffered extensive damage from over 100 projectiles, but was restored. In 2008, it became the co-cathedral of the Đakovo-Osijek Archdiocese.

The book emphasizes the church's role as a spiritual center, but also its resilience to wartime destruction, earthquakes, and historical challenges, making it a symbol of unity and permanence for Osijek.
