The first two pictures were taken at the edge of an open pit for brown coal mining. It is part of the "Rheinisches Braunkohlerevier" (rhine brown coal area, http://de.wikipedia.org/wiki/Rheinis...aunkohlerevier
(sorry, there is only a german article on wikipedia) ).
It is located in the west of germany and the biggest brown coal mining area in europe. They are digging up to 400 m deep, which is about 290 m below sea level.)
The secound picture is a bucket-wheel excavator ("Schaufelradbagger" in german). They are used for digging the brown coal and also the surface cover above the coal.
They dig up to 240 000 m^3 per day, have a weight of up to 14200 tons and a height of about 90 m.
Here is a picture of the whole digger:
The third picture is a rebuild of a tower which is was used vor surveying and mapping in the 19th century.
It is neraby a outdoor museum showing old houses and buildings from the 18th and 19th century.
