  1. Most likely a water source like a spring that gets collected to supply fresh water to houses, you also see those a lot in mountains.

    Or the entrance to some secret military 🤫

  2. Horsetail grass. In German known as Schachtelhalm or Katzenschwanz. They have rhizomes which can pierce through the soil up to 6 feet (1.8 m) in depth. If you have them in your garden you properly will have them forever.

  3. Entry hatch (vented with an air filter) for water supply underground structures.
    Brunnenstuben, wells, valverooms etc.

  4. This is ventilation for the bunkers where we keep the nation strategic reserves of cheese and wine, like most bunkers these days.

  5. it can be many things, it is a standard cover for shafts which are not closed with cast
    iron lid.
    sockets (springs)
    ventilation shafts
    bunkeremergency exits
    controlshafts (for many different things)

  6. It’s the watersupply… spring water is collected below. There are tours you can visit them. We keep them high for have a save supply whiteout power anf only the waterpressure from the higher grounds. That’s our safety for bad times. Like around 1 week water for everyone without power

  7. We should have been more like

    “oh shit”

    “Holy moly he found it”

    “Just run away as fast as you can”

  8. It’s ventilation system for the top secret International Off-World Technology Research facility. It’s basically like Switzerland version of Area 51

  9. (§3,¶47): When burying a dead body on Swiss territory, a proper disposal container must be used. (See §7¶38) The container must not be deeper than 1.65m in the ground. Violations are be punishable by fines up to CHF1000.
