I cannot understand the lack of logic in the WHS List. I appreciate that nominations occur year after year but more work and effort should be invested so as to have a coherent and logic WHS List.
I think that transnational nominations as well as WHS clusters (counting as 1 WHS on the list) could be a smart way of decreasing the overall number of WHS without excluding them from the list.
For example, I like the idea of grouping Wooden Churches per country, per religious identity or per architectural style. However, I would also expect the same principle to be applied retroactively by UNESCO on other sites that have been inscribed individually in the past. Something in the line of Most important Gothic Churches in France (instead of having the ones in Paris, Reims, Amiens, etc. inscribed separately or Roman Villas in Lazio instead of Villa Tivoli and Villa Adriana as 2 WHS.
The same applies to having mixed cultural and natural sites that are very close to each other (or overlapping each other in certain cases) as grouped WHS, for example Pienza and Val d'Orcia.
This would not only decrease the sheer size of the WHS List in general, but also it would help reduce the number of European WHS, Catholic/Christian WHS, etc. Then, I think, we wouldn't have such a Europe-dominated WHS (or at least the number of separate WHS would go down and the list would be more logical and coherent.
What do you think?
