Underground Boundaries

WHS whose core underground boundaries extend beyond those at ground level. (The underground areas extend beyond the surface boundaries such that the land above the inscribed areas is not a part of the inscribed site core area (though it may be a part of a buffer zone). Thus it is possible to stand somewhere at ground level OUTSIDE the WHS whilst land some distance underneath is INSIDE the inscribed core boundary.)

Champagne The UNESCO Maps of Reims and Epernay show the inscribed areas as pink for overground and a blue line for underground (The "Caves"). The latter sometimes extend beyond the former – but are always within the buffer zone (Orange)
Mining Cultural Landscape Erzgebirge Beyond the boundaries of the inscribed surface areas there are numerous underground elements some of which are not even included in the surface buffer zone. See (link) which show dotted lines for "Nominated property underground" extending way beyond any inscribed overground zone. E.g the entire element of Dippoldiswalde Mediaeval Silver Mine (1-DE) and the Freiberg location (4-DE). The Nomination file states - "On the Saxon side, in some cases, for linear elements a standardised buffer zone between 5 and 10 meters in width was determined. Structures located underground were only allocated with a buffer zone when these are reflected by function-specific installations or archaeological remains above ground. Otherwise, above ground (construction) measures will have no effect on these mostly very deep-lying structures."
Tarnowskie Góry Lead-Silver Mine See UNESCO Map with solid lines for "Surface Nominated property" and dotted lines, extending way beyond these, for "Underground Nominated property (Protected at surface)". (It is not clear whether this "protected at surface" means that the surface is an "official" (UNESCO) buffer zone)

Do you know of another WHS we could connect to Underground Boundaries?

Send it to me!

A connection should:

  1. Not be "self evident"
  2. Link at least 3 different sites
  3. Not duplicate or merely subdivide the "Category" assignment already identified on this site.
  4. Add some knowledge or insight (whether significant or trivial!) about WHS for the users of this site
  5. Be explained, with reference to a source
