Ludwig's WRAP-UP
In summary, "once there were" is a versatile phrase for introducing past conditions, particularly when contrasting them with the present.

Alternatives like "there used to be" or "formerly there were" may be more suitable in those situations. Remember to use "once there was" for singular subjects and "once there were" for plural subjects.
