On further inspection, it appears to be a pretty narrow walkway between two church buildings. It looks like there's barely enough room for two people to pass each other, let alone room for a horse. Plus, I see no reason why the churches would want a horse rambling through their small entrance way. So I am going to say no horses is correct and resolve this. The other possible answer is to call the church and ask, which I would totally do for the laughs if it comes down to it.
