621
In a fine environment, with the known view.
It has an extra room for watersupply.
Very rare, a crack in the roof. Most bunkers are after all these years still in an excellent condition.
Some detail on the roof and what do you think of the hacienda.
In 2016 Wilco Tak was able to get inside.
All steel parts have been stripped.
The typical feature of a 621. One Scharte directly to the wall, the other leaves a gap of some inches.
The usual warning text.
