What was the only organization dedicated to helping Jews escape from Nazi occupied Europe to be sponsored by it's own government in exile.
You are looking for something about the size of a large suitcase. If you find this object, you will know the answer to this question. It is located near to the Monument to the Heroes of the Ghetto in Warsaw. This is not a cache, visiting Poland for the first time, I didn't feel I understood the environment well enough to establish a proper cache. This will however, be the first Geocaching location in Poland so I claim a first. If you are interested in the Second World War, or you are Jewish, this is an important site to visit. The coordinates were captured with an Etrex Vista, the terrain was open and the accuracy was good to within 16 feet.
FIRST EVER Geocache in Poland!!
