Back in the old 'hood?

This is Monterey Square in Savannah. Since my first visit here in 1999, I've been curious as to why there's a square in this city named after my town when Savannah is much older. The answer, as The Lizard discovered, is that back during the Mexican War Monterrey, Mexico, was spelled differently, (at least by the Yanquis) and this square was named after a military victory in that city. Still, it's kinda cool to find a seeming trace of the old 'hood in such an unlikely spot.
