This is presumably a well-known town and church.
Art UK has not been able to trace the copyright holder. The picture was painted about 20 years ago, so there must be a good chance of identifying the artist. There is an illegible signature bottom right. It could be that the signature reads 'Tuzo', rather than that being the title, but that is only a thought.
A close-up of the signature is attached.
Perhaps General Sir Harry Crawford Tuzo, GCB, OBE, MC (1917–1998) 
According to the NYT , his interests included painting.
Andy, thank you for your suggestion.
The ODNB lists him as Sir Harry Craufurd Tuzo and notes that he was a
keen amateur painter, among other interests. I haven't been able to find any of his pictures online yet. The ODNB might be able to give us a contact.
Marion, the signature in your attachment seems to contain some additional letters, starting with what appears to be an R to the lower right hand side of the second large letter. Is it possible to obtain a better image or can you work out those additional ones from what you can see?
Here's an enhanced version of the signature. It just becomes more blurred if try to make it larger. I alos thought there were other letters below the larger mark: perhaps RU ...but that's very uncertain.
Perhaps someone could suggest the likely location, possibly Italian/ Adriatic. It can't be called 'Tuzo' since no such place appears to exist, save as a Mount Tuzo in Alberta after the lady (Henrietta T.) who first climbed it and the [John] Tuzo-Wilson Seamounts not far off the California coast named after that geologist.
I wondered about Portmeirion, given where the pic is: but apparently not...
Perhaps the enhanced signature could be read as either 'Lewis' or 'Jones' (which may not help much in narrowing it down...)
Well, whatever the signature, it certainly looks like the work of a recreational painter.
The church looks Greek or Russian Orthodox in style. The buildings on a hillside remind me of Veliko Tarnovo, Bulgaria. So I think it's either a scene in Greece or the Balkans, which then raises the possibility that the signature is in Greek or Cryillic alphabets.
Given the nature of the collection, it may well be that this is the work of a present or former member of the National Assembly for Wales, which is a political body, not an art institution.
There are, it seems to me, four characters under the signature; I wonder if it's a year, beginning "200"?
The Art UK entry lists the date as 2000.
There are likely to be people still working at the Assembly who were around when the painting was acquired - institutional memory is a real thing - so enquiries there, either through the Press Office or their General Enquiries point on the website may come up with something. (Apologies to Marian if she's already tried this route.)
Alison, thank you for suggesting this. I had emailed the National Assembly for Wales, as we have a contact there, and I have asked the ODNB whether they could put me in contact with the family of Sir Harry Tuzo.
For the purposes of comparison, attached are two versions of Harry Tuzo's signature.
But if the date is 2000 it cannot be Sir Harry Tuzo - he died in 1998.
I'm not wholly convinced the word/?signature reads 'Tuzo' - it's an odd way of doing a capital 'T', and it could equally be a lower-case 'p' (or 'g') with letters before and after.
Or as Tim suggests, should we be thinking Greek or Cyrillic?
Marion, are there any marks or labels on the back of the work?
Hi there. I have just seen this.. I am Harry Tuzo's daughter.. sadly this is not his signature. I do have a couple of paintings by him and they are not in this style at all. Sorry !
Hi Victoria, thank you for confirming that this isn't your father's work.
Marion, are there any marks or labels on the back of the work? Also, could the name be Tom ..... It looks like the first letter of each name have been exaggerated, and smaller case letters complete each.
(sorry, I shouldn't be doing this at this late hour) "...the first letter of each name has...".
I have a feeling this might be something made for the tourist or decorator market by a more or less commercial artist, in which case we are highly unlikely to identify the painter.
In addition, the scene may be a capriccio of sorts, as opposed to a faithful depiction of an actual site.
Canaletto also painted capriccios for the tourist market.
That is one way to look at it, Kieran, but it hardly helps us here, where we are dealing with something on a quite different level of magnitude. I'm reminded of something Cezanne said: "Monet is only an eye, but my God, what an eye!"
