From 1699 on the Alexander Church was used for evangelic Lutheran services. During this year Sweden became the ruling faction. The Catholics bought a house with several additional buildings and out of a barn "a church like building" was developed. During 1700 to 1803 Hannover ruled, Catholics were not allowed to build a new church. Only in 1810, when Oldenburg took over Wildeshausen the Catholics were allowed freedom to follow their religion. They built their church, which opened on November 24, 1811. The church had to be closed again due to structural mistakes, making it unsafe. In 1824 the current church was finally built, without a tower. The tower was erected in 1910.
