The Cranny is used to hide some of your resources in the event the village is attacked. Resources that are stored in the Cranny cannot be stolen by attackers. The amount of resources hidden is dependent on the level of the Crannies that are in a specific village.
After one Cranny has reached level 10, additional Crannies can be built.
Requirements: None
How the Cranny works
The amount of resources protected depends on the level of the Cranny. If you have multiple Crannies in the same village, their protection capacities are added together.
Tribe differences
Crannies are particularly effective for Gauls, as their Crannies protect twice as many resources.
Teuton Heroes have a base plunder bonus of 20% when they accompany an attack. This reduces the effective protection provided by the defender's Crannies.
Plunder bonus and Bags
Bags equipped by an attacking Hero also provide a plunder bonus that reduces the effective protection of the defender's Crannies.
For example, a 10% plunder bonus reduces the effective Cranny protection to 90% of its normal capacity.
If a Teuton Hero accompanies the attack and is equipped with a Bag, the Bag's bonus is added to the Hero's base plunder bonus.

Crannies and farming
Crannies are especially useful if your village is being raided regularly and you cannot yet defend it effectively. Reducing the resources an attacker can steal makes your village less profitable to farm.
