A motte is a raised area of ground, a earthen platform, which had a castle built on top. The motte was "accompanied by a walled courtyard, or bailey, surrounded by a protective ditch and palisade"[1]. They were sometimes built on older structures like barrows or fortification_type=ringfort. When man made, the earth to form the motte came from the ditch dug around it.

Confusingly, in Ireland, they are mostly referred to in older maps and in the vernacular language as "moat", when a moat is defined as "a deep, broad ditch, either dry or filled with water, that is dug and surrounds a castle, fortification, building or town"[2].

How to map

Ideally, draw the area, or, if not discernible on aerial imagery, add a node with the following required tags:

If it is known to be built on top of an older structure, the appropriate tags can be added as well.
