A cranny is a building that hides resources from attackers. At level 1 it hides 200 of each resource (300 for Gauls), and at level 10 it hides 2000 (again, 3000 for Gauls). It is advisable to build a Cranny before your Beginners Protection ends, upgrading it to cover the resources you normally hold, particularly overnight accumulation. If a player upgrades the village's Cranny to level 10, they can then build additional Crannies in that village. There is no limit in building second or third crannies.
