- The map shows the fortification plan from 1940 for the fortifications in Hanko position (H-position), which was later renamed as Harparskog-line. The map has been made so, that the geographical north is located on top of the map and the geographical south at the bottom of the map. Scale of the map is 1:20 000, meaning that one centimeter on the map, is 200 meters in nature. For this presentation the size of the maps have been adjusted in order to fit them better to the display. Because of this, the scale is not completely accurate when looking the maps from the display.


- The number of the structure is written with a black pencil and usually placed on top of the structure.

- Strength class of the structure is marked with a Roman numbers. The strength classes vary from I to V, with the class I being the best one.

- The blue number next to the structure indicates how many men the structure is able to accommodate.

- In case that the bunker or open position is armed with a gun, the caliber of the gun is marked with a red pencil.

- It was possible to combine different map symbols together, in order to create a proper tactical symbol.

- Red arrow marks the firing line for machine gun.

- Blue arrow marks the firing line for gun.

- Red square marks additional objects in the defensive line, which were not originally marked in the map.

Tactical map symbols



- Accommodation bunker/dugout serving as a field dressing station.

- Please note that the map symbol can and will vary from the explanation in the fortification card and what can be found from the terrain.

- The marking +sik indicates "Sikaari", which  means a periscope system.

- The letter T, which appears with few of the structures means a tunnel like structure.

- The Finnish texts use systematically the word "Korsu" for the structures, which translates as dugout. Still as some of the structures are made from concrete, I would think that the English word bunker is a better word to describe these kinds of constructions.  In this presentations I have tried to identify the structures either as bunkers, which are made from concrete or as dugouts, which are mostly made from wood.
