Geocache Description:

Naissaar - the largest island of North-Estonia (Swedish – Nargo, German - Nargen). Island is the same size as Estonian capital and located about 10 km north of Tallinn.

Since the time of the tsar, Naissaar has been designated as a military stronghold for the defense of Tallinn and St. Petersburg. Military constructions notably changed the face and the nature of the island. The fascinating ruins of the island will take you back to a time when the lives of the people did not cost anything. You will discover coastal batteries built more than 100 years ago as well as Soviet era fortifications. It will take two days to find all the WPs and explore everything at a leisurely pace.

Your task is simple- in each next WP you must find a combination of black painted letter and number.  Numbers you should write down and letter you should use to project next WP. Use this method until last WP (M). 

Set your GPS settings to:

  • North reference – GRID
  • Bearing - Degrees
  • Distance – meters/kilometres

In the start coordinates you must use letter N to project the next WP. The value of N is 3.

A- 129m, 165° (In)
C- 256m, 167° (On doors)
D- 669m, 294° (In, from above)
E- 290m, 340° (In)
F- 247m, 190° (On wall)
G- 2.28km, 208° (In)
H- 715m, 171° (On wall)
I- 634m, 218° (In, up, in)
K- 193m, 178° (in)
L- 749m, 345° (In, on doors)
M- (In & above)
N- 1.69km, 329° (Foundation rock)
Q- 325m, 038° (In)
S- 1.97km, 117° (On stone)
T- 175m, 347° (In, up)
U- 1.70km, 345° (Under)
W- 510m, 343° (Foundation for wire rope)
X- 678m, 199° (In)
Y- 1.11km, 270° (On wall)

After you have visited all the waypoints, you will get the final sum which will be ABCDE. If the sum is smaller than five digits, add the necessary amount of zeros at the beginning of the sum. If sum is more than five digits, remove extra digits from the end of the sum.

The final cache can be found at: N 59° [ACA+BC].[CDE+BBC] E 024° [EA-CD].[EDE-CDC-BED]
