The copper bell, which weighs several thousand pounds, was reported missing by the manager of the church. It was made in 1889 at a Baltimore factory before being shipped to San Francisco and has survived both the 1906 earthquake and a major fire at the church.
The bell was moved to the church’s new location at 1111 Gough Street in 1971, where it was put on display in the garden.
Investigators are trying to find out if there is any surveillance video from the area that may have captured the thieves.
Police said they are not sure if the stolen bell is related to other recent copper thefts in the city. They have also notified local junkyards and recycling centers to be on the lookout.
The church is offering a reward for any information in regards to the case.
