Is the Wooden Tserkvas one an extension of the Southern little Poland or the wooden churches of Slovakia?
SCRAP THAT just checked and it seems they are separate, apparently the SLP churches are not the same because:
They have their own spatial-planning structure and do not contain towers in the form of domes and tent-frame roof
I have no real specialism on Carpathian region ecclesiastical wooden architecture but I'm not convinced it really needs 3-6 different world heritage sites (depending on what you count).
But then I would probably argue for more 20th century modernist architecture to be added, so perhaps it isn't really so different?
