This is the only intact artefact in the ex-Führerhauptquartier "Wehrwolf" (in Stryzhavka near Vinnytsia in Ukraine).
This firefighting reservoir (10mx15m and variable depth) is commonly referred to as "the pool".
The geolocation of this firefighting reservoir is: 49°18'20.02"N 28°30'7.85"E
It is one of my first attempts in Agisoft. Some beginners errors are obvious.
This a small part of my six-year research about FHQu "Wehrwolf".
