Mount Olivet Cemetery is a Catholic cemetery located just south of Dubuque, Iowa in Key West, Iowa. It is one of the two main Catholic cemeteries for Dubuque area Catholics. The cemetery is located near Saint Joseph's Catholic Church in Key West. While people from that parish are often buried at Mount Olivet, the cemetery itself is not considered part of the parish. The cemetery offers regular ground burial, as well as columbarium and mausoleum entombment. Originally, the cemetery was known as the Key West Burying Ground. In 1901 it was given its current name of Mount Olivet Cemetery. At that time the Mt. Olivet Cemetery Association was formed. This board - led by 11 trustees - started by removing bodies from the Third Street Cemetery - which had been located behind St. Raphael's Cathedral. St. Joseph's Chapel Mausoleum is located at the northwest corner of the cemetery. The mausoleum was built in 1990, and was later expanded. This building has crypts for mausoleum entombment, as well as columbarium niches for cremated remains. The building also houses a small chapel which is used for the final committal ceremonies.
