Does the abbreviation for Saint in a church name require a period?

Question

In referring to a local church, does the name "St Giles" require a period after the "St"? I was told that to add a period confuses it with the abbreviation for street.

Answer 1

Generally we include the "." in St. in American English although looking online I'm seeing in British English they do not include the "."

Because of the way addresses work I've never heard of it being confusing

Example: St. Giles Church Street

The street goes at the end while the saint would always come before a name.

Does that make sense?

Answer 2

The correct way to write it is "St. Giles." The confusion with street should not matter because the street abbreviation comes at the end, not the beginning (example: St. Giles vs. Giles St.). St Giles is standard for British English, but not American.
