There are two Cemeteries by this name. The first is under the existing church (Royal Presidio Chapel, San Carlos Church, and San Carlos Cathedral) which was constructed between 1792 and 1794. Following the start of construction, the cemetery was moved to what is now the 500 block of Webster Street outside the presidio walls. It remained there until 1834 when the current cemetery (San Carlos Cemetery) was established. Several graves were relocated but not recorded. Persons dying before 1792 where buried in the first cemetery and those dying between 1792 and 1834 were buried in the second cemetery.
