This one's past is pretty well concealed, but the architecture and the covered-over inscription at the top of the building are good clues that it was originally a synagogue. (Here's where you can confirm such hunches. Just look up this address — 276 Buffalo Avenue.) Apparently, the church across the street used to be a synagogue as well, but it doesn't have any of the tell-tale signs (or at least none of the ones I'm familiar with).
