The Ilūkste Roman Catholic Church is to the North of Unity Square. The first stone church in Ilūkste was financed by the Plater-Sieberg dynasty of noblemen between 1754 and 1769. The current church was built in 1816. In 1861, it was taken over by the Orthodox Church, but it was returned to a Catholic congregation in 1920. The church was restored in 1921. The interior can be viewed during worship services.
