During my summer vacarions in the beautiful island of Lesvos, I placed this multicache.
The cache
First of all, you have to climb up to the church and count one by one all the steps, until you reach the main entrance in church's courtyard (see photo "entrance"). The total number of steps are number X.
!!! Caution, the number you have to count, is not the number referred in the sign before you start clmbing !!!
Then go to the church entrance. In front of the entrance, there are three gravestones. One of them has only a name and two years, a birth year and a death year. The description on the gravestone has the following form:
NAME SURNAME
ABCD - EFGH
And now some maths to find the final coordinates:
N39 19.(X*5+C*10+E)
E026 10.(A+C) (G-C+A) (F-C+E)
The final spot is not too far.
