There are flowers/foliage inside the window to the left - so it's likely that it was a big event at that building rather than a day out that happened to be pictured there. The guesses at a wedding or harvest festival seem plausible - they look dressed for mild summer weather.

I'd guess that either the group or the location has to be local, but not necessarily both. I have a few photos were I know that the stated photographers address doesn't hold any relevance to the person pictured.
