No, Ben, I’m talking about the area that is labeled “Part of ST. MARTIN” in Hammond atlases. It is completely separated by another parish.

While we’re at it…
There is a city “in” Iowa (i.e., politically part of it) which is almost completely surrounded by Omaha, Nebraska, and lies across the Missouri River (which it touches at one point, hence the “almost” above) from the rest of Iowa. The main road from downtown Omaha to the airport goes through it, IIRC.
