As of my last knowledge update in September 2021, there is no specific “World Heritage Cellars of Hercegkút” that is recognized as a UNESCO World Heritage Site. It’s possible that there might have been new developments or nominations since then, but as of my last update, this specific site does not appear on the list of UNESCO World Heritage Sites.
UNESCO World Heritage Sites are places or areas of outstanding universal value, such as cultural, natural, or historical significance, and they are recognized and protected by UNESCO to preserve them for future generations. The list of World Heritage Sites is continuously evolving, with new sites being added and existing sites being reviewed periodically.
If there have been any recent updates or developments regarding the “World Heritage Cellars of Hercegkút” or any other sites in Hungary, I recommend checking official sources such as UNESCO’s official website or the Hungarian government’s cultural and heritage authorities for the most up-to-date information.
