This is one of six Marinepeilstände (MP) observation towers that were built on high points. They are the most obvious symbol of German construction. Each observation slit of a tower observed for one particular battery and was fitted with range finding equipment.
South-east of Gun Battery Dollmann, is Marine Peilstand und Meßstellung 4 (MP4); the bunker was built in 1942 and has walls 2 metres thick and 5 floors. Observations and targeting were made through the openings in the front of the bunker.
