There is a recent pubblication about an ancient church in Viterbo (Italy). The church is listed in wikipedia as

http://it.wikipedia.org/wiki/Chiesa_di_Santa_Maria_Nuova_(Viterbo)

The timber roof is very interesting, and the most part is dated XV century. You may have a snapshot of the roof through the download of the sample from the book  https://dl.dropboxusercontent.com/u/4629082/scaricar/sample.doc

The information about the book are linked here:

But in Italian language....
