A  ravelin is a detached, triangular outwork that is placed in front of the curtain wall of a fortification.

The letter D in this diagram marks the locations of ravelins in a star fort or bastion fort.

How to map

Place a node at the centre or draw an area along the outlines of the ravelin and tag it with defensive_works=ravelin.
