According to Steve Baker, official historian for the City of Monrovia, there are time capsules buried in Library Park. Don't know about anyone else, but I'd love to know what's in them. That pleasure will belong to someone else as there doesn't appear to be any plan to dig them up anytime soon.
- Under the City Christmas tree in front of one of the original City Hall stones is a plaque. A time capsule buried in 1953 rests there.
- The Monroe rock marks a time capsule from 1936. Rumor has the capsule not being buried until 1958, but this is not absolutely verified.
- Another time capsule was buried by the Monroe rock during the City's Centennial in 1987.
