This desinged began with a brief research about Crotia and Zagreb and I found that according to a tale, the Zagreb name came from "Zagrabiti" which means Dig!. The referance comes from a tale that long long time ago, a group of soldier was passing by Zagreb land and they had no water. The captain of the team puts his sword to the land and when he retrieves his sword, water came out from soil, lots of them. So the name has a very natural and cultural meaning.
