Church of the Immaculate Conception

The Church of the Immaculate Conception is a sandstone structure featuring a square central tower topped with a pyramid-shaped spire and round-arch stained glass windows positioned above three entrance doors. The building displays characteristics of Romanesque Revival architecture throughout its design and construction.

Construction took place between 1909 and 1911 using locally quarried sandstone materials. The building then served as the Cathedral of the Diocese of Rapid City from 1930 until 1962.

The church has hosted Latin Mass services since 1992, serving as a center for traditional Catholic worship practices in the community. This makes it a living place where visitors can experience how certain religious traditions continue today.

The church sits at the intersection of Fifth and Cathedral Streets and remains active for regular worship. Visitors should understand that this is a functioning place of prayer where respectful behavior is expected.

This was the last cut stone building completed in Rapid City using locally quarried materials. After its construction, building practices in the city shifted away from this traditional stone method.
