help please!

[Tom Priestly]

I am preparing an illustrated talk on "my camino" for my univ's
alumni travel club and have collected hundreds of pictures which I am
now winnowing - from the photos we took and ones from the web.
There is one that I cannot identify (I must have found it on a
web-site): a church interior, looking along the nave to the altar:
relatively unadorned style, with semi-circular arches, white walls
and stone imposts; two pulpits; three statues on the altar; and an
enormous scallop shell (white with black edging) behind the altar.
The huge scallop makes this a good picture to include in my talk!
Where is this please? I did not see it myself (I missed many of the
architectural sights). I can attach a picture to a private e-mail, if
my description is not good enough.
Thanks in advance!
