Cathedral of Our Lady of Perpetual Help

The Cathedral of Our Lady of Perpetual Help is a modern Catholic church in Rapid City featuring a rectangular structure with a curved reinforced concrete roof clad in Mankato stone. The building combines contemporary design with traditional religious elements throughout its interior spaces.

The cathedral was built to address space limitations at the previous St. Mary's Church, with a bishop deciding to create a new facility for the diocese. A community member donated the land needed for this construction project.

The cathedral displays eighteen tall stained glass windows featuring religious figures and an Italian marble altar beneath a large image of Mary. These artistic elements shape the interior and create a space for both private prayer and communal worship.

The church holds regular services throughout the week with multiple Sunday Masses offered at different times to accommodate various schedules. Visitors should check service times ahead of their visit, as these may vary seasonally or during special religious holidays.

The building underwent a major expansion project that added educational facilities and communal spaces in the basement level. This expansion allowed the cathedral to strengthen its role as a community gathering place and expand its programming offerings.
