Whilst searching for Pumping stations I looked in more detail than before at the Erzegebirge Nomination file. This has enabled me to "complete" a Connection suggestion which I have been trying to do for some time!!Underground Boundaries
WHS whose core underground boundaries extend beyond those at ground level.
There are 2 ways in which "underground" elements of WHS can be defined in terms of boundaries at surface level and this Connection identifies examples of the second. The first has been the more "normal" approach for sites with underground elements (E.g Cultural sites such as Blaenavon, Wieliczka, Goslar, Qanats and Natural ones such as Geomunoreum Lava Tube System)
a. The inscribed surface boundaries totally "encompass" the inscribed underground areas beneath them - either exactly or by covering a still wider area.
b. 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.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 the Nom File Maps
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.

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)Tarnowskie Gory
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)
