Around the initial coordinates you are able to find several
memorials of people that have influenced the area, or events that
have taken place in the village.
Seven of these memorials have something written in metal. To
calculate the final coordinates you need to find all of the objects
and solve the mystery behind them. The key needed to solve the
mystery is 1816, 1776, 1667, 1580, 1473, 1320, 1277. The hidden
hint will help you confirm the seven memorials, but it will not
help with the mystery.
NOTE: Be careful when unveiling the cache. There is a risk of
losing it for good.
