It looks like UNESCO uses the term “Property of Cultural Interest” more often than other alternatives (“Asset of Cultural Interest”, “Cultural Interest Asset”), as seen on the following unesco.org pages (a total of 9 hits using the advanced google search to look only on unesco.org pages).

Kate: Are you sure that it refers to the entire town? I think it may be saying that in 1931 the wall was given one denomination and then 1993 another. On the other hand, when I've encountered "conjunto" (and I do a lot of texts similar to yours for Mexican sites--and into US English), I usually use "group" or occasionally "complex" and it IS referring in these cases to a set of structures.

Oops, I removed the name of the town to keep it confidential but realised that the sentence is possible now confusing.

It is the TOWN ITSELF that is a 'Conjunto Historico'. Not the wall refered to in the first part of the sentence.

Sorry about that.
