I wasn't able to identify this church directly, but on the web page of la chiesa di Santa Margherita (the Church of St Margaret), it's described as "Chiesa Antica Santa Margherita"; the old church of St Margaret.

I can't even identify which road it is on... if it is indeed on a road at all. It may be behind some other buildings, and accessed by a walkway. There is a small branch street which comes off the Via Passerin d'Entreves (the street that our hotel, the Auberge De La Maison, is on) called Via San Margherita which SEEMS to run toward this church (and which would make sense given its name). This church appears to have been in that general direction. I've therefore tagged it as being on that street, even though I'm not 100% sure of it. (Google Street View is useless for this, and the satellite imagery in this area looks like it came from Sputnik.)

There is a newer church on the Strada della Brenva which was built, I believe, in the mid to late 1960s, and which will be seen later in this gallery.
